Do not show non-workspace packs when installing pack dependencies

When using the "CodeQL: Install pack dependencies" command, we would
show packs that are located in the package cache or distribution. Since
there are no dependencies to install for these packs, these options are
not useful.

This will filter out any packs that are not in the workspace folders
when showing the quick pick. This should exclude most packs if you are
in a workspace without the `codeql` submodule and should be a lot more
intuitive in those cases. If you are in a workspace with the `codeql`
submodule, it will still show all the packs.
