chore: re-enable API compatibility checks post 3.0 release

[lprimak]

API checks were disabled because there is no "base" 3.0 version to test against.
Once 3.0.0 is released, the API compatibility checks can be re-enabled for minor releases

• Committers: Use "Squash and Merge" to combine all commits into one when merging a PR when appropriate.

Trivial changes like typos do not require a GitHub issue (javadoc, comments...).
In this case, just format the pull request title like [DOC] - Add javadoc in SessionManager.
