Exit on errors when running Git (#4889)

* Exit on errors when running Git * Skip pulling changes entirely * Enable pipefail when generating diffs * Cleanup * Shallow repo check * Echo GITHUB_SHA update * Check if GITHUB_SHA exists before using it * Move GITHUB_SHA validation to validation script * Rely on cat-file return code * Check if DEFAULT_BRANCH exists * Change dir when checking DEFAULT_BRANCH * Show git branches * Don't switch branches * Check GITHUB_SHA only when needed * Ensure we have permissions before interacting with the repo * Remove the DIFF_CMD variable * Move TEST_CASE_RUN and RUN_LOCAL init up * Validate if Git repo and if SHA exists * Move validation function * Change dir when getting branch names * Move debug messages up to be less verbose * Move branch validation in a function * Fix linting errors

-## Main script
-
-The file `linter.sh` is the main script that is called for the process and loads all other scripts as functions.
-
-## Functions
-
-The additional files in the folder are functions to help streamline the main build process and allow for easier maintenance.

- `buildFileList.sh`
-  - Functions to help find files that were modified, or need to be scanned
