Allow `glab mr checkout` to output status during execution
# Context When doing a checkout on a MR from `gitlab-org/gitlab`, it takes a couple of seconds (sometimes more) on a top-tier macbook pro. During this, the command doesn't give any information of what is going on, and it appears as if the command either failed or is stuck. ## Proposal We should pipe the output from git during `glab mr checkout`, going from: ```bash $ glab mr checkout <MR_ID> # ... some seconds of wait $ ``` to ```bash $ glab mr checkout <MR_ID> # content below is from executing the git command: Updating files: 100% (4100/4100), done. Switched to branch 'branch-name' $ ```
