build(deps): remote obsolete gradle home cache cleanup property

- this was toggled on for 3 workflows, it is on by default not: removing
- this was *not* toggled on for unit tests because we have observed problems before,
  but now it is the default for everyone and I am assertively/hopefully assuming
  they have fixed the problems we have seen (or will do so shortly) so letting it
  become enabled with its new default setting

Note that if workflow runs start failing, this was the comment leading to upstream
information:

gradle-home-cache-cleanup is temporarily disabled to investigate cache pollution issues
