New release with no maximum version constraint

[bodgit]

Can we please get a release of this module with the maximum version constraint removed so we're not stuck on version 5.x of the GitHub provider.

According to the Terraform Documentation, modules should ideally not specify a maximum version constraint.

I'm also waiting on support to control the commit message format but just fixing this would unblock me from being able to upgrade the GitHub provider.

It was commented in February in #165 that something might be released soon, we're now in June with no release(s).

Likewise for your GitHub team module, as that's also pinned to < 6.
