LGTM, and is there any other char in name?

As repository names described:

All code points must be either a hyphen (-), an underscore (_), a period (.), or an ASCII alphanumeric code point

current pattern: /([a-z0-9_-]){2,}\/([.a-z0-9_-]){2,}$/gi should be OK for all cases.

And as Usernames, Organization names and Team names says dot(.) and dash(-) is not allowed. Actually, the pattern for the name part: ([a-z0-9_-]){2,} is more relaxed than what is actually needed. IMO, it is acceptable, as this pattern is just a filter for some basic checks on UI.
