Add drupal/rel_to_abs

For daily emails, I want all links to be absolute URLs so they work when
embedded in the sent emails.

This module does this.

As there is no Drupal 11 compatible release, I've had to add the Lenient
Composer endpoint and add patch the rel_to_abs module to make it D11
compatible.

If everything works, I'll update the issue and mark it as RTBC.
