[ci] Update Bonk to OpenCode 1.18.18

[elithrar]

Update both Bonk workflows from OpenCode 1.15.13 to the current 1.18.18 release.

Recent Bonk auto-review runs in workers-sdk and cloudflare-os exit during provider initialization before selecting the Claude Opus 4.8 runtime. A controlled Bonk run with OpenCode 1.18.18 completed successfully.

• Tests
  • Tests included/updated
  • Automated tests not possible - manual testing has been completed as follows:
  • Additional testing not necessary because: this only changes the OpenCode version consumed by two GitHub Actions workflows; both workflows pass YAML parsing and actionlint.
• Public documentation
  • Cloudflare docs PR(s):
  • Documentation not necessary because: this is an internal CI workflow dependency update.
