feat(renovate): add previous major versions' schemas + global self-hosted config (#5294)

* feat(renovate): introduce "global" JSON schema

As part of Renovate 41.x we introduced the separation of "repo" and
"global" configuration into separate JSON Schema documents.

* feat(renovate): add previous major versions' schemas

As noted in #5285, it would be convenient to have the previous versions
of Renovate JSON Schema files, for use after the major version is bumped
and no longer supported.

As a starting point we can look at the major versions in use in 2025,
retrieving them from the `docs.tgz` on the last release in a given major
series.

This also requires we:

- add the `$id` and `id` fields
- run `prettier` on the schemas
- make sure validation doesn't try running in `strict` Ajv mode
- make sure validation ignores custom properties
- make sure spell check doesn't flag partial regexes like
  `|[Cc]ontainer` as a typo

Closes #5285.
