Emit all shellcheck errors using github action toolkit annotations and check for tab indentation

[cartercanedy]

Tabs are problematic when rendering previews of shell scripts, as it results in a disparity between the position of expected rendered characters and where they may actually be rendered on the screen, and having mixed space/tab indentation in the same file is generally problematic as well.

Type of Change

• [x] Bug fix
• [x] Refactoring

Description

• Emit all errors found within the changed files using gh actions toolkit annotations, before, the workflow would fail on the first shellcheck invocation that had an error emission
• Add a tab indentation check to enforce consistency in code style
• removed all current tab indentations that I've found in shell scripts

Testing

Verified using workflow runs within my own repository

Impact

Helps provide complete error information from both shellcheck and tab indentation detection

I need those implemented here to pass the new shellcheck ci workflow. You should be able to rebase your changes on top of mine

@ChrisTitusTech I'd recommend committing this before pulling in any shell scripts to get better shellcheck errors and catch formatting issues
