Use espup

[SergioGasquez]

Use espup instead of rust-build script for installation. This should also solve #15 as it removes the call, and relies on the version check to espup.

Time-wise, the action takes around 2 minutes, the same as the rust-build scripts used to last.

Also, I've created another branch that improves the cases covered by the CI as many arguments are not covered atm, if we endup merging this PR, I'll create another one for it.

This is looking pretty good, as far as I can tell. Thanks for making these updates, hopefully it will be a bit more reliable.

~2 minutes is acceptable I think, I would still like to get it down a bit but it's reasonable. Something we can work on in the future.

Out of curiosity have you tested the workflow with any of the repositories currently using it (eg. esp-hal) or are we just relying on the local CI? In theory our CI should be fine, but I'd just like to be certain that things work as expected. You can use owner/repo@hash to run an unpublished action (see the docs).

Once espup is async, this should be improved!

I've run esp-hal five times with the new changes and 0 failures so far: https://github.com/SergioGasquez/esp-hal/actions/runs/3732477054

Thanks for testing it out!
