ci: Improvements on the mirror and prebuilt flow (#386)

* Remove redundant git lfs pull command

The `git lfs pull` command in the GitHub workflow is redundant and has been removed. Additionally, the `sync-lfs.sh` script has been updated to push all LFS objects to the origin repository.

* using force push instead of trying to merge

* Bumping ssh agent to 0.9.0

* Syntax
