Please define outside collaborators in code

[AntonyBishop]

Hi there

We now have a process to manage github collaborators in code:
https://github.com/ministryofjustice/github-collaborators/blob/main/README.md#github-outside-collaborators

Please follow the procedure described there to grant @peter-bcl access to this repository.

If you have any questions, please post in #ask-operations-engineering on Slack.
