fix(ci): compile firmware-action in examples

- we had some breaking changes in firmware-action since last release
- example tests need to know if to download firmware-action executable
  from release, or if to compile on the fly
- problem is that the example CI checks for changes of current HEAD vs
  MAIN, not vs latest release
- this patch should fix this behavior
