Display number of unpushed commits

[idagelic]

Is your feature request related to a problem? Please describe.
Git context updating that is available by running daytona info currently displays the number of uncommited changes in the project. This does not mean our changes are necessarily in sync with the git provider when there are no uncommited changes.

Describe the solution you'd like
We should also add information regarding the diff from project branch to origin branch similarly to the "Your branch is ahead of origin/main by 1 commit" message that appears when checking status of repo with unpushed commits.
