Only allow scoped extension pack names

When packaging an extension pack, unscoped extension pack names are not
allowed and calling `codeql pack bundle` will fail with an error. This
command will be called when running a variant analysis, so these packs
will not work for a variant analysis.

To improve the user experience, we now only allow scoped extension pack
names. This means that the user will now have to enter a scope when
creating a new extension pack.
