Sækja Unity CLI 1.0.0.20008

Highlights of 1.0.0-beta.8 (full notes at the release notes URL):
- unity close closes the Unity editor that has a project open, and is available in a released build for the first time. Neither the default nor --force saves your work.
- The command that updates the CLI itself is now unity self-update; unity upgrade keeps working as an alias.
- Repository creation now works on Bitbucket through bkt and on Azure DevOps through az, alongside the existing gh, glab, and tea integrations.
- On Windows, unity install no longer reports a successful install as failed when you are not an administrator, and installing modules into a protected folder now works.
- Interrupting a download with Ctrl+C no longer leaves the taskbar showing progress forever, orphans the elevated installer, or leaves the install lock behind.
- Commands no longer stall after their work is done on a signed-in, opted-in profile, where reading the OS keyring could block for tens of seconds.
- unity vcs uvcs review reads and answers Unity Version Control code review comments from the terminal.
