fix: remove playground2 (#42)

Additionally, some changes to terraform action so it will stop spamming
with changing merge-commits
- `merge_commit_title` and `merge_commit_message` are set only if
`allow_merge_commit`
- `squash_merge_commit_title` and `squash_merge_commit_message` are set
only if `allow_squash_merge`
