Remove redundant devDependencies automerge override

[ErisDS]

Summary

• Removes the repo-local Renovate rule that overrides automergeType to branch for devDependencies
• The org-wide config (tryghost/renovate-config) already automerges all dependency types using automergeType pr, making this local override redundant
• Aligning with the org default simplifies the config and ensures consistent behaviour across repos

Test plan

• Verify Renovate still automerges devDependency updates (now via PR instead of branch)
• Monitor that dependency update behaviour remains as expected

Walkthrough

The pull request removes a packageRules entry from the Renovate configuration that previously enabled automatic merging for all devDependencies. The removed rule had automerge: true and automergeType: "branch" settings. The remaining packageRules entries for other dependencies (rollup/plugins, lexical, vitest) remain unchanged. A minor whitespace adjustment is also applied to the JSON structure.

8-14: ⚠️ Potential issue | 🟡 Minor

Fix indentation on line 9 for consistent JSON formatting.

The opening brace for the first packageRules entry is missing proper indentation. All other entries in the array use 4-space indentation before {, but this one is flush left.

Proposed fix

   "packageRules": [
-{
+    {
       "groupName": "rollup + plugins",
