[CI] fix issue when apply format (#6019)

Fix issues hit when apply format.
1. tmp diff file is not opened binary form, don't need to encode.
2. add contents write to "Check code formatting" workflow for commit and
push change.
3. put main branch to different path to avoid issue when checkout head
branch to same path.
