Feature description

As described 4 years ago in #6343 it would be nice to have automated dependency updates.

Why do you want this feature?

Currently it has to be checked by hand if dependencies are upgradeable.
A dependency update tool would do that automatically.

Don't get me wrong: Updates still need to be tested but it's a lot easier if a PR already provides a update.

Additional information

We already had this discussion in the past (#7154) and well:

1. As it turns out people doing updates is not the norm, app/programs are better at it

   I will reopen it when Taco is on vacation 😂

   Taco is gone since 2 years :(

2. Many mentioned problems have been fixed (e.g. grouping versions together, amount of PR, forking mode, etc) or can be customized

From the last years of experience I can highly recommend using renovate as it's open source, quite good configureable, self-hostable and has way less problems when compared to dependabot.
