Erlang manager

[Taure]

Tell us more.

Renovate is handling elixir today but we want it also to work for erlang. Today we can get the PR that we have new dependencies but we need to solve a lot of things to update the lock-file in our CI workflow.

It would be nice if the lock file could be updated and handled in the PR from renovate. I have done it in 3 PR:s.

1. feat(manager): add rebar3 manager for Erlang dependency extraction #42025 - so this is for rebar.config parsing and rebar.lock reading
2. feat(manager): add rebar3 lock file and artifact support #42026 - lock file / artifact support - rebar3 upgrade
3. feat(manager): add rebar3 range strategy support #42027 - range stragey support
