chore(deps): setup renovate and bump images for examples

[phisco]

Description of your changes

Setup renovate to use renovatebot/renovate#25896, also bumps the used images to the latest available.

I have:

• Read and followed Crossplane's contribution process.
• Added or updated unit tests for my change.

By the way your Renovate config file still uses the config:base preset, you should change it to config:recommended, because Renovate v36 changed the term. 😉 That way you can always search for the config name and find the correct docs.

If you're using the Mend hosted app version of Renovate, you may want to wait a while before merging your PR. It takes a while before the hosted app gets updated to a newer version of Renovate!

• Renovate docs for config:recommended preset
• Renovate docs, when is the Mend Renovate app updated?

@HonkingGoose, we do use the version hosted by Mend, any pointer to check the version being used?

I think the only way is going to the Mend dashboard (See link in a Renovate PR footer) and reading the debug logs for a recent Renovate run. The debug logs always have a line that says what Renovate version ran.

Please subscribe to this discussion I opened to ask a Renovate maintainer:

• Finding current version used for the Mend Renovate hosted app on github.com? renovatebot/renovate#25913
