chore(renovate): extend scop/common preset

[scop]

I'm consolidating my Renovate configs (and soon some other common things) to a common repo, cf. ref https://github.com/scop/common/blob/main/default.json

No plans to make any drastic changes and I'll update extending projects if I figure out I may be doing something in the common that conflicts with them.

I think .json doesn't allow code comments for ease of implementing a parser, though I'm not sure if the specific parser used by renovate is permissive about this.

[scop]

The usual JSON does not, however Renovate's parser does, and they explicitly recommend using the .json suffix when there are comments nevertheless (and they don't support .jsonc at least according to docs) 🤷

Renovate supports JSONC for .json files and any config files without file extension (e.g. .renovaterc). We also recommend you prefer using JSONC within a .json file to using a .json5 file if you want to add comments.

Hm this did not work the way I thought it would, it appears ignorePresets was overridden rather than being merged, as the dep dashboard popped up again, #589. Need to have a look.

Thank you!
