Revert "java/intellij: Move man pages to share/man"

Apart from the share/man move, the plist fix was not correct:

pkg-static: Unable to access file /wrkdirs/usr/ports/java/intellij/work/stage/usr/local/share/intellij/lib/commons-lang3-3.11.jar:No such file or directory

The above listed file has nothing to do with Python. Additional
files added were also incorrect. Packaging fails as a result.

The share/man move will be restored in a later commit after getting
some sleep.

This reverts commit e71303202ab8b168f9bc05e204d60261c99c56b1.
