Updates git-tools to the latest version based on your branch.
Usage:
git tool-update [-sourceBranch <string>]
Notice: Old versions of git-tools did not update the git-tools. In those
cases, running git tool-update will produce no output. For old versions, cd
to the folder where git tools is installed, perform a git pull (and ensure
you're switched to the branch you want to track, like main), then switch back
to your project where you are using git-tools and run git tool-update.
Updates git-tools to the latest of the corresponding branch. If omitted, defaults to the branch the tools directory has checked out, which is usually main.
