Broken symlink CHANGES.rst.gz

[Lee Maguire]

/usr/share/doc/python3-keyring/CHANGES.rst.gz is a link to changelog.gz

But changelog.gz is not included in the python3-keyring package.

python3-keyring_23.5.0-1_all.deb

I think it's a bug in Ubuntu's debhelper package.

I am not adding the symlink manually, instead I'm using `dh_installchangelogs -k CHANGES.rst` command.

Ubuntu patches dh_installchangelogs to not install the upstream changelog:

    - dh_installchangelogs: Do not install upstream changelog in compat level
      7 and higher to avoid pointlessly bloating installed packages.

However it seems like Ubuntu's patch does not handle the -k option well: it removes the symlink, but not its target.
