[Request]: Update name with one that complies with the GNOME HIG

[TheEvilSkeleton]

Describe the request

I propose to change the name of Tooth to one that complies with the GNOME HIG. The GNOME App Naming guidelines discourages the use of puns. I'm not sure, but "Tooth" is a pun right?

What do you think? We can brainstorm if this proposal is accepted.

Implementation Details

• This should be an option in settings.
• This should be only available to some fediverse backends. (Include which ones on the above field).
• This is client-only (and shouldn't sync with the instance).
• This follows the GNOME HIG.

Admittedly, I searched for an existing issue after I opened this one. My apologies for opening a duplicate issue #28.
