Modernize release flow based on 5.x

* Pin firrtl version to 1.6.0
* Pin chiseltest version used in testing to 0.6.2
* Switch to unipublish
* Remove 3.6.0 as MiMa previous version as unipublish won't work with it
  Will restore checks with 3.6.1 release, this is mitigated by the fact
  that every backport to this point has been checked.
* Update Github Actions versions
* Remove CI for documentation and website (handled by main branch)
