fix: issues with scripts, no aws (#4)

Fixes the following issues with the `web/git` Ansible scripts.

- Updates cache before installing `python3-pip`.
- Forces `terraform init` configuration during provisioning.
- Requires user to set an `endpoint_url` to get the backup file from S3.

In addition, I'm removing the last of AWS from the repository:

- The routing uses Hetzner now, so let's get rid of all of that.
