Rework CI

[SergioGasquez]

• Use a bash script
  • Can be used locally by modifying the template_path and executed from outside your local esp-template repo (no cargo command works inside that folder because of the syntax errors in all the files)
• Only cover the simplest and more complex cases of options
• act is not working out of the box:
  • rust_ci.yml needs to be moved from the .github/workflows/ folder as it fails to parse it due to the weird syntax, again.
    • Did some further testing and solved this by moving the rust_ci.yml to a different folder, .github and the on the post-script.rhai move it to the .github/workflows/ if the user accepted the CI prompt. Not very clean, but it allows using act, happy to improve or remove this workaround.
  • After moving the rust_ci.yml, it works, just make sure you specify the GH TOKEN, required for Xtensa toolchain action: act -s GITHUB_TOKEN="$(gh auth token)" -j verify

Thanks @jessebraham for the ideas to improve the workflow! Any feedback on how to improve it further is more than welcomed!

I really like the idea of moving functionality to a locally runnable script 👍
