Automate provider version bumps

[salasberryfin]

Description

After creating a forked version of CAPI projects (core, providers, etc.) we now need to take care of publishing mirror releases ourselves. While looking at #785, there should be a mechanism to simplify the process and automate as many steps as possible. Turtles maintains a list of URLs pointing to all pre-built providers in a configuration file here. We can use updatecli to automate creation of version bump PRs.

Options

• Easiest solution is to schedule executions of this automation and let it check what the latest release is for each of the projects. updatecli is smart enough to then only generate a PR if there are changes to the configuration file.
• We could also test the possibility of using a dispatch webhook so events in forked repositories can trigger actions in Turtles to run updatecli.
