(release-maven-plugin referred to as RMP)

I am very sorry to explain here, and request to restore the previous merger.

Here are the Reasons:

Ignorance of the RMP, I have just seen the pr #4350's files changed, Especially ignored the commit messages. I feel that changing the version impacts a number of too many files, based on experience, I mentioned the previous pr.

After an in-depth understanding of the RMP, there is no compromise solution, unless the extension RMP increases the extension implementation of the global version variable, but there is no need to go the other way.

Pls, revert the wrong pr, I will raise more issues to discuss in the future to improve the quality of pr.
