[FEAT]: Support GitHub repository custom properties

[yu-iskw]

Describe the need

GitHub just announced the feature of GitHub repository custom properties. We can use the information of custom properties to apply rules to repository in GitHub organization(s). It would be good to support the feature in the terraform provider as well. By doing that, we will be able to manage custom properties and rule sets in terraform.

Unfortunately, this feature is not released on the API yet. Once support is added in the API, we can implement it in the provider.

Looks like a REST API is in public beta now. Is that enough to get started? Thanks!

[kfcampbell]

Ideally there would be more than just a GET. We could make a data source with the existing endpoint, but not a full resource.

There are more endpoints here (incl. creation): https://docs.github.com/en/rest/orgs/custom-properties?apiVersion=2022-11-28

Ahh my mistake, thanks for correcting me!

[roeishuster]

Hey, do you guys plan on adding this in an upcoming provider update?

[kfcampbell]

GitHub's SDK team unfortunately does not have the bandwidth to take this on ourselves, though we're very receptive of PRs!
