Update release.yml to include internal and github_action labeled PRs

[quiet-node]

Problem

The release.yml in the repository is a tool that automatically generates release notes for hedera-json-rpc-relay, currently covering PRs labeled as enhancement, bug, documentation, and dependencies. A new category for internal changes should be added to include PRs labeled as internal and possibly github_action.

Solution

Update .github/release.yaml to include internal changes, as shown below:

changelog:
  exclude:
    labels: ['wontfix', 'question', 'duplicate', 'invalid']
  categories:
    - title: 'Enhancements'
      labels: ['enhancement']
    - title: 'Bug Fixes'
      labels: ['bug']
    - title: 'Documentation'
      labels: ['documentation']
    - title: 'Dependency Upgrades'
      labels: ['dependencies']
+   - title: 'Internal Changes'
+     labels: ['internal', 'github_action']
