[KYUUBI #4247] build/mvn should use the exact version defined in pom.xml

### _Why are the changes needed?_

As mentioned in #4247, it seems to be better that using the same maven version with master. Thus, modify the version check logic in `build/mvn` from equal or greater to equal.

### _How was this patch tested?_
- [ ] Add some test cases that check the changes thoroughly including negative and positive cases if possible

- [ ] Add screenshots for manual tests if appropriate

- [x] [Run test](https://kyuubi.readthedocs.io/en/master/develop_tools/testing.html#running-tests) locally before make a pull request
