fix: make renovatebot's ignorePath and grouping of non-major updates work correctly

[kenneth-rosario]

The renovate configs currently in use is not correctly ignoring the docs and experimental folders, and seems to not group non major updates together.

• The previous renovate config ignorePaths was not working due to a current issue with renovate itself where ignorePaths is being overwrited by the coinfig:base defaults. The suggested fix is to use globalExtends property. Discussion used: https://github.com/renovatebot/renovate/discussions/14793
• Changed config to use the group:allNonMajor extension which ended up grouping non-major versions correctly.

Tested by forking repo, changing versions manually, and then running a locally cloned renovate bot against my fork with the updated renovate config file.

Example of how non major grouping would look like:

(side note, probably this should have been a non-triggering type like chore or ci / build vs. fix)?
