Parallelize CI by splitting Unit Tests and Integration Tests on different Github actions

[jofrevalles]

This PR resolves #273 by modifying runtests.jl and CI.yml so the unit tests and integration tests run on different Github Actions.

this is awesome! thanks!

i suspect that precompiled packages are not getting correctly cached because every CI run is precompiling all test dependencies and takes around 5-7min. it might be a good moment to fix this.

I guess we can cache for each Julia version, right? I suppose this is not possible for different Julia versions. But how can this be done, in a sequential way? Since right now all the Actions are deployed at the same time.

if you use @info we can get nice colors in the logs

Suggested change

	println("Running tests for group: $TENET_TEST_GROUP")
	@info "Running tests for group: $TENET_TEST_GROUP"

Sure! I think I will remove that, I am putting this now since I think this ENV is not properly set by CI.yml.

so the cache works and should be caching for each CI job type (e.g. one cache for "unit tests" - "ubuntu" - x86_64 - Julia 1.11).

but i still don't why it takes so much time to precompile for testing.

also, you may want to use the matrix instead of writing different jobs:

and then you pass the env var like this:

https://github.com/EnzymeAD/Reactant.jl/blob/c664414990141ab04455c49a793a3b9144f2182b/.github/workflows/CI.yml#L130

Yes, I changed that. I am already doing this.
