This change updates the Node Version Manager version file to the latest
long-term release version of Node.js, v20.11.1, and the Node.js Package
Manager package file to require Node.js version v20 or later.

Additionally, all Node.js modules have been updated, as some packages
required additional accommodations to be made compatible with this
version of Node.js.

As part of this, the `.commitlintrc.js` has been rewritten from CommonJS
to ECMAScript. There should be no impact on the behaviour of Commitlint,
but this was was a requirement to allow Commitlint to continue using it
for configuration.

In all TF-A commit messages, the first line must comply to the
following format:

  type(scope): description

Although the conventional commits specification says that the scope
above is optional, we have made it mandatory in TF-A and the following
error message is printed if no scope is provided:

  scope may not be empty [scope-empty]

However, this can be too restrictive for some types of commits. For
example, it is typically hard to choose a scope for documentation
patches which modify several documents of different natures.

Lift this restriction in the tools and leave it up to the developer to
decide whether a scope is needed or not.

This change replaces cz-conventional-changelog with cz-commitlint, which
automatically configures Commitizen using our commitlint configuration
file. Currently, we use some manual Javascript magic to load our
Commitizen configuration into commitlint (the opposite of what's
introduced by this change), which can be removed.

With this change, we also move our commitlint configuration into a
new `changelog.yaml` file. This file holds the same data as `.cz.json`
previously did.

This change simply reorders the `body-max-line-length` and
`header-max-line-length` fields to be in the order that most people
mentally expect. This has no actual function impact.

This avoids errors when mixing letters and numbers in the scope.

This change introduces a new NPM run script to automatically generate
the release changelog, as well as bump version numbers across the
code-base and create the release tag.

This script runs [Standard Version] to execute this, which is a tool
designed around automating substantial parts of the release process.
This can be done by running:

    npm run release -- [<standard-version args>]

Standard Version expects the project to adhere to the [Semantic
Versioning] convention which TF-A does not, so you may need to specify
the version manually, e.g.:

    npm run release -- --release-as 2.6.0

Individual steps of the release process may also be skipped at-will,
which may be necessary when, for example, tweaking the changelog:

    npm run release -- --skip.commit --skip.tag

Standard Version is configured by the `.versionrc.js` file, which
contains information about the Conventional Commits types and scopes
used by the project, and how they map to the changelog.

To maintain continuity with the existing changelog style - at least to
the extent possible in the move from manual to automatic creation - a
customized changelog template has been introduced, based on the
Conventional Commits template provided by Standard Version.

This template package extends the Conventional Commits template package
by introducing support for parsing the Conventional Commits scopes into
changelog sections, similarly to how they were previously organized.

[Semantic Versioning]: https://semver.org

This change adds checks for the `Change-Id` and `Signed-off-by`
trailers. These are already required by Gerrit, so they have been
configured as warnings as an early heads-up after committing without
needing to push.

This also renames the commitlint configuration file to align it with
the style used by Standard Version when it's eventually introduced:

    `commitlint.config.js` -> `.commitlintrc.js`
