This should say something about go-mod-ts-mode, at least which files
it's supposed to support and for what purpose.

Aren't the files's base name always exactly "go.mod" and nothing else?
If so, the regexp should be augmented, because we don't want to use
this moder for, say, foogo.mod or fubar-go.mod, right?

Thanks.
