Suggestion: Add RenovateBot or dependabot

[Urigo]

Just a suggestion to add RenovateBot to track new versions of the codegen more easily and keep up to date with it.

If you'll add tests we can even think about connecting this repo to the codegen's Connected Build

Thanks for the suggestion @Urigo, I'll look into that. I didn't know about RenovateBot, but it looks interesting
