* fix(workers/global): parse `.jsonc` files
As noted in #44033, this leads to cases where
`renovate-config-validator` can't parse a repo's `renovate.jsonc`.
This doesn't currently affect when Renovate itself runs fully.
* test(workers/global): add coverage for `getParsedContent`
This test also validates that the fix introduced in the previous commit
correctly fixes the issue.
This also makes sure that if we change the default JSON-like filenames,
we'll validate that it can be parsed, based on the filename.
