(Have the ability to) Ignore 'shared repositories' if cloning recursively
Problem to solve
When running glab repo clone -g group/subgroup -a=false -p --paginate all repositories in 'Shared Projects' are also pulled and cloned. I'm not sure if this is the expected default, but it would be good to have the ability to exclude those (as they are often linked elsewhere).
Proposal
Introduce an additional flag to include/exclude (depending on the default) any Shared Projects linked to a particular (sub)group.
Further details
I appreciate Shared Projects might not be as common.
