Changed Renovate grouping to bump @tryghost/limit-service on its own

[ErisDS]

Summary

Splits @tryghost/limit-service out of the "TryGhost admin support packages" Renovate group so its version bumps come out as their own PR.

Why

Unlike the other packages in that group (color-utils, custom-fonts, members-csv, timezone-data), limit-service bumps are feature-tied: each new entry in its lib/config.js allowlist is paired with consuming BREAD-service / limit-helper code here in Ghost. We need the version bump to land as a reviewable, single-package PR so it can be coordinated with the consuming change (and so a flaky CI run on an unrelated admin-support bump doesn't block it).

No other behaviour changes — limit-service still respects the rest of the existing config (schedule, automerge windows, dashboard approval for majors, etc.).

Test plan

• Renovate config-only change; no runtime impact.
• Verify next Renovate run opens an isolated Update dependency @tryghost/limit-service PR rather than bundling it into the admin-support group.

Walkthrough

This pull request modifies the Renovate dependency management configuration to separate @tryghost/limit-service into its own dedicated package grouping rule. The change removes @tryghost/limit-service from the shared "TryGhost admin support packages" matchPackageNames list, which previously bundled it with @tryghost/members-csv and @tryghost/timezone-data. A new packageRules entry is added to match only @tryghost/limit-service, assigning it its own groupName for independent dependency update handling.
