rename this project to tails-sysadmin?

Hi!

We have had at least one (experienced sysadmin!) user misfile a ticket (#18168 (moved)) presumably because this project is called "sysadmin" and likely to come up as a good candidate to file sysadmin issues in general.

This is also a bit of an exotic project: all other projects (but one other exception, which i think we should also get rid of) follow a more "flat" namespace convention, without any sub-groups.

So I wonder if it might not be best to move this project from the path tpo/tpa/tails/sysadmin to tpo/tpa/tails-sysadmin. Renaming paths in GitLab is fairly lossless: redirects are kept and things just keep generally working.

Of course, that would mean removing the tpo/tpa/tails group, but I'm not sure what the goal of that group is in the first place. We might want a toplevel tails group, or perhaps a tpo/tails group at some point, but I don't quite see what this particular group here brings us.

Thoughts?
