Currently, a human creates the PR. It will be good if mimic the process Dependabot provides.

We can create a GitHub bot that will run a designated amber script in the repository and apply the changes on the PR itself after a manual button press.

The script would then have to:

1. Check if there are conflicts with the upstream branch (if so then do not continue)
2. Pull changes from base branch
3. Clone Amber repository
4. Move stdlib files to the latest version docs
5. Push the changes to the PR
