[Bug] `gpMgmt/bin/pythonSrc/ext/` files are not cleaned after installing Cloudberry

[tuhaihe]

Apache Cloudberry version

main

What happened

running the configure command with the option --with-pythonsrc-ext, then make install --directory=~/cloudberry, some files are not cleaned up:

[gpadmin@cdw cloudberry]$ git status
On branch main
Your branch is up to date with 'origin/main'.

Untracked files:
  (use "git add <file>..." to include in what will be committed)
	gpMgmt/bin/pythonSrc/ext/PyGreSQL-5.2/
	gpMgmt/bin/pythonSrc/ext/PyYAML-5.4.1/
	gpMgmt/bin/pythonSrc/ext/psutil-5.7.0/

What you think should happen instead

They should be cleaned up after installing the Cloudberry.
