chore: process labels on pull requests

[HonkingGoose]

Changes

• ⚠️ Add write rights to pull requests for dessant/label-actions ⚠️
• Add configuration to process labels on pull requests

Context

We created a new label:

renovate/.github/label-actions.yml

Lines 154 to 167 in fb56b1f

	'pr:no-done-comments':
	comment: >
	Hi there,
	You are using simple `done` comments which cause a lot of noise.
	Instead, please use GitHub's web interface to request another review.
	Please read our [contribution guide](https://github.com/renovatebot/renovate/blob/main/.github/contributing.md#resolve-review-comments-instead-of-commenting) to reduce noise.
	Good luck,
	The Renovate team

But we forgot the extra permissions and setup in the .github/workflows/label-actions.yml file. 😄

The README.md for dessant/label-actions has the explanation for the configuration options.
