Introduce a working github_repository_prereceive_hook resource

[joestump]

What does this PR do?

This adds a new resource for managing pre-receive hooks in GitHub Enterprise.

Example HCL

resource "github_repository_prereceive_hook" "code_reviews" {
  name        = "require-code-review"
  repository  = "hello-world"
  enforcement = "enabled"
}

TODO

• Write integration tests
• Update docs

It looks like we are getting a failure when running the tests. Here is the error

--- FAIL: TestAccGithubRepositoryPreReceiveHook_basic (4.78s)
    testing.go:568: Step 0 error: errors during apply:
        
        Error: GET https://api.github.com/repos/terraformtesting/foo-xd3xek6kxn/pre-receive-hooks?per_page=100: 404 Not Found []

This is not required as we should be checking what's in state matches reality. This can be accomplished using an import state verifier

{
				ResourceName:      resourceName,
				ImportState:       true,
				ImportStateVerify: true,
			},

This is a check against the API; not state? I don't have an importer for this resource. I can skip validating against the API entirely though if that's preferred (I copied this pattern from the webhook tests).

@tracypholmes this is a feature that's only available in GitHub Enterprise. I don't believe the main GitHub website supports this API endpoint. I ran the tests against our GHE install and they passed. I'll get the other comments addressed shortly. 👍
