Subject: [PATCH] Keep Maven Central out of Renovate's lookup path

Renovate runs have been aborting with "External host error causing abort
- skipping", so no dependency updates land.

Renovate's maven manager appends Maven Central to every Maven
dependency's registryUrls unconditionally, regardless of the
repositories declared in the poms (modules/manager/maven/extract.js,
cleanResult). The maven datasource uses registryStrategy "merge", so
Central is queried for every dep, and a 429 or 5xx from Central is
turned into an ExternalHostError that can take the whole run down
(modules/datasource/maven/util.js).

Every dependency in this repo is org.cyclops.*, served by GitHub
Packages, so pinning that groupId to its real registry removes Central
from the lookup path entirely. Rules for the commented-out mekanism and
refinedstorage deps are included so re-enabling them does not
reintroduce the problem.

Also applies the config migration Renovate reports: matchPackagePrefixes
becomes matchPackageNames with a glob.
