Update documentation to reflect the new Jakarta Specifications and change namespaces

Documentation needs to be analyzed to determine the following:

1. Do we need to document compatibility changes for spec X?
2. What examples/code snippets need to have package/signature changes?
3. Define the new specification versions where applicable.
4. Change "Jakarta EE 8" references to "Jakarta EE 10". Or better yet remove the version reference.
5. Check the minimum requirements, e.g. Java version, section.

This list may or may not grow, but those are the basic places to start. We could consider breaking this into components if that makes sense. Just create a new JIRA and make this JIRA it's "is parent of".

Do note that asciidoc does support variables and we should use those where applicable.
