Removed package-local Renovate preset from theme-translations

[aileen]

The translation auto-merge rule for @tryghost/theme-translations has officially moved into the shared theme preset in TryGhost/renovate-config (theme.json5), and no theme repository extends the package-local renovate-config.json anymore.

This removes the now-unused local preset:

• Deleted packages/theme-translations/renovate-config.json
• Dropped it from the published files list in package.json
• Removed the README references, including the migration TODO that tracked this cleanup

The shared theme preset is now the single source of truth for Renovate rules.

Verified with npm test in packages/theme-translations (all tests pass).

Walkthrough

This PR removes the package-local renovate-config.json file from the theme-translations package. The changes include updating the files whitelist in package.json to exclude the configuration file from published distributions, removing the file entry from the README contents section, and condensing the Renovate auto-merge documentation note by removing references to the deprecated local configuration preset.
