[jakartaee-platform-dev] Updated the jakartaee-api release job and repo

[Scott Stark <starksm64@xxxxxxxxx>]

It was pointed out that the current release job always releasing the 4
jakartaee-api artifacts was producing newer lower versions of
previously released artifacts. See
https://github.com/jakartaee/jakartaee-api/issues/188 and
https://github.com/jakartaee/jakartaee-api/issues/187 for details.

The https://github.com/jakartaee/jakartaee-api.git repo has been
updated to use a
maven-ci-friendly(https://maven.apache.org/guides/mini/guide-maven-ci-friendly.html)
versioning scheme along with new properties that allow you to release
the api jars independently.

The platform CI wiki page has also been updated to describe the new release job:
