Add default description and tags for runner label

[baolsen]

Makes it easier to use.

  runner_label = "codebuild-${var.name}-$${{ github.run_id }}-$${{ github.run_attempt }}"
  tags = {
    runner-label: local.runner_label
  }
  description     = "Runner label: codebuild-${local.runner_label}"

Also add to examples.

For me, it's the missing tagging in general for the aws_codebuild_project resource. Please bump that to the top of your list. Thanks! :)

Hey @smcaulay-peaksware, thanks for the feedback.

At the moment at least the aws provider tags are pulled through.
Are you already using provider tags, and you want to add some kind of custom tagging on top?
Just want to understand the use case a bit better.

Let me know if you think this PR #84 will work for you
