Fix trailing whitespace in automerge workflow

[Copilot]

Yamllint detected trailing spaces in .github/workflows/automerge.yml causing validation failures.

Changes

• Removed trailing whitespace from lines 54 and 57 in the approval check step
• Verified YAML syntax remains valid after cleanup

Notes

Line-length warnings remain but are consistent with existing workflows (ci.yml, dependabot-automerge.yml) and do not affect functionality.

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• https://api.github.com/graphql
  • Triggering command: /usr/bin/gh gh pr list --head copilot/automate-merge-pull-requests (http block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
