Describe the change

The workflows here:

https://github.com/premail/website/blob/main/.github/workflows/bullet-list-update.yml
https://github.com/premail/website/blob/main/.github/workflows/signoff-update.yml

should automatically add the labels 'Status: Available' and 'Type: Documentation' when they auto-create these issues, so we don't have to.
