@jencull do you need me to add anything else in this PR?

this came up yesterday in team chat "Wait, there's GITLAB_BOT_TOKEN in the user.env, but the PAC_GITLAB_TOKEN is only in the preview-template.env, and it looks like PAC_GITLAB_TOKEN is the one that's required for webhooks. So we need to set both in other to make it work"
