Modify runtests and CI settings for JET

[ytdHuang]

This PR merges two CI config file into a single one Runtests.yml.

Also, merge the test/code-quality/runtest.jl into the standard test/runtest.jl file but keep the environment separate for JET. This allows the developers to run both test groups (Core and Code-Quality) in local with one single command:

(QuantumToolbox) pkg> test

but also run separately in GitHub CI pipeline.

Summary of this PR:

• merge CI-Core.yml and CI-Code-Quality.yml into Runtests.yml
• merge code-quality/runtests.jl into standard runtests.jl file

I understand your idea. We can try to do the following if you agree:

• We remove the code-quality environment
• In the runtests.jl file we add the Aqua.jl and JET.jl packages through the Pkg.jl package.
• We include the code quality test files
• We use the CI file you propose here

In this way, the Aqua.jl and JET.jl packages are not present in the Project.toml file, but they are installed only in the case of the Code Quality test.

What do you think?

[albertomercurio]

As far as I know, having QuantumToolbox in the Project.toml (without the Manifest file) would install the latest stable version of the package, and not the local dev package. That's why I installed the local package directly from the CI

[ytdHuang]

Yes, you are right !

[albertomercurio]

I don't think we need this, since we are already using the local del version of QuantumToolbox.
