Automatically check for GitHub updates on the CACs

[alex-l-kong]

Is your feature request related to a problem? Please describe.

It isn't efficient to manually have to update this repo across several CACs. We should create a Task Scheduler job that allows for automatic fetching and updating.

Describe the solution you'd like

We will need to create a task, along with a trigger during significant downtime (ex. 5am). This task needs a supporting script that does the following:

1. Check for updates on remote, if none then exit. If there are, however...
2. ...run git stash (non-admin users should NOT be making manual changes to the repo directly on the CAC)
3. Run git checkout main
4. Run git pull

This script will need to be saved to a .bat file and provided as an argument to this task.

Additional context

We should start off on Angelo Lab CACs. We could add this to the main repo with instructions in the README.md how to setup, not sure how many users outside our lab would use this though.
