Use a better API to check organization membership.

This API (https://docs.github.com/en/rest/reference/orgs#check-organization-membership-for-a-user) better handles edge cases like the user having a pending invitation or not having granted the org scopes.

I just tried this branch against a recent bp-dev machine and it doesn't seem to work for me! 🤔 I get:

Failed to impersonate Actions admin user.

The exact same command-line arguments seem to work for the main branch:

Thanks @simon-engledew! I had the arguments to IsMember in the wrong order. 🤦

Ok, that seems to have worked!
