Ability to update the latest matomo release with mix task

[aerosol]

When ua_inspector is serving as a dependency, there is no way to point mix ua_inspector.download to the latest release.

This can be solved via either:

• using the "latest" GitHub releases redirect as per https://docs.github.com/en/rest/releases/releases?apiVersion=2022-11-28#get-the-latest-release
• adding a command-line option handled by the mix task allowing to overwrite whatever UAInspector.Config currently hardcodes under @remote_release

Happy to submit a PR once I know the preferred way to go.

Thanks
