[BUG]: The `github_repository` resource churns on `vulnerability_alerts` if not explicitly set

[stevehipwell]

Expected Behavior

When creating a new repository with the github_repository resource, this should not churn if vulnerability_alerts is not set.

Actual Behavior

If vulnerability_alerts is not set it will constantly churn.

Terraform Version

n/a

Affected Resource(s)

• github_repository

Terraform Configuration Files

resource "github_repository" "test" {
  name         = "test"
}

Steps to Reproduce

Apply the above resource and then run a plan.

This issue is being caused by a missing Computed: true value on the schema. I'll open a PR to fix this, but long term this attribute should be deprecated and handled by it's own resource.

It also looks like if a repository is created with an explicit value for vulnerability_alerts that doesn't match the default it will also churn.

[stevehipwell]

The code to fix this is currently in #2476 but I'm planning on opening a seperate PR for this change before that gets merged.

I'm having this issue running acceptance tests:

 data_source_github_repository_autolink_references_test.go:44: Step 1/2 error: After applying this test step, the plan was not empty.
        stdout:
        
        
        Terraform used the selected providers to generate the following execution
        plan. Resource actions are indicated with the following symbols:
          ~ update in-place
        
        Terraform will perform the following actions:
        
          # github_repository.test will be updated in-place
          ~ resource "github_repository" "test" {
                id                          = "tf-acc-test-uzqg7"
                name                        = "tf-acc-test-uzqg7"
              - vulnerability_alerts        = true -> null
                # (35 unchanged attributes hidden)
        
                # (1 unchanged block hidden)
            }
        
        Plan: 0 to add, 1 to change, 0 to destroy.

@acouvreur acceptance tests on this branch?

My feature branch from main

@acouvreur I'm confused as to what you're saying? This PR is intended to fix the flaky tests, so if you've got a branch from main it will have the issues this PR fixes present.

I'm sorry about the confusion, I wanted to point out that this issue is still happening and is preventing me from contributing properly.

So it was more something like: "this issue is still relevant and happens to me, can confirm."

I'm just showing support for this PR 😀
