Bug: Add labels if they are missing when trying to auto-label

[jmeridth]

Describe the bug

If a label is mentioned in .github/release-drafter.yml for auto-labeling and it is missing, we get an error like the following:

HttpError: You do not have permission to create labels on this repository

Since we're running the label with:

permissions:
  content: read
  pull-requests: write

That is to be expected.

To Reproduce

1. add auto-labeling action from this repo to a repository
2. wire-up release-drafter to a label that doesn't exist
3. error

Expected behavior

If a label is mentioned in release-drafter.yml and doesn't exist, it should be created before being used. This might require higher permissions of the action. TBD.
