Split out `formatRepo` and `formatRepoSelection`

This splits out the two templating functions that are referenced in
the documentation. The two functions were previously available in
the source code, but they were not named with the method names that
the documentation referred to.

This closes https://github.com/select2/select2/issues/2993.
