[9.0] Cutover to the new transport version system (elastic#135046)

This commit updates the latest transport version ids to use the new
gradle managed system. It also adds a test to ensure new constants are
not added to TransportVersions.java.

-     * ADDING A TRANSPORT VERSION
-     * To add a new transport version, add a new constant at the bottom of the list, above this comment. Don't add other lines,
-     * comments, etc. The version id has the following layout:
-     *
-     * M_NNN_S_PP
-     *
-     * M - The major version of Elasticsearch
-     * NNN - The server version part
-     * S - The subsidiary version part. It should always be 0 here, it is only used in subsidiary repositories.
-     * PP - The patch version part
-     *
-     * To determine the id of the next TransportVersion constant, do the following:
-     * - Use the same major version, unless bumping majors
-     * - Bump the server version part by 1, unless creating a patch version
-     * - Leave the subsidiary part as 0
-     * - Bump the patch part if creating a patch version
-     *
-     * If a patch version is created, it should be placed sorted among the other existing constants.
-     *
-     * REVERTING A TRANSPORT VERSION
-     *
-     * If you revert a commit with a transport version change, you MUST ensure there is a NEW transport version representing the reverted
-     * change. DO NOT let the transport version go backwards, it must ALWAYS be incremented.
-     *
-     * DETERMINING TRANSPORT VERSIONS FROM GIT HISTORY
-     *
-     * If your git checkout has the expected minor-version-numbered branches and the expected release-version tags then you can find the
-     * transport versions known by a particular release ...
-     *
-     *     git show v8.11.0:server/src/main/java/org/elasticsearch/TransportVersions.java | grep '= def'
-     *
-     * ... or by a particular branch ...
-     *
-     *     git show 8.11:server/src/main/java/org/elasticsearch/TransportVersions.java | grep '= def'
-     *
-     * ... and you can see which versions were added in between two versions too ...
-     *
-     *     git diff v8.11.0..main -- server/src/main/java/org/elasticsearch/TransportVersions.java
+     * DO NOT EDIT THIS FILE.
      *
-     * In branches 8.7-8.10 see server/src/main/java/org/elasticsearch/TransportVersion.java for the equivalent definitions.
+     * Transport version must now be added with the new transport version system. See docs/internal/Versioning.md
