build: stop building and testing on `alpine` and `debian`

[RaisinTen]

After https://github.com/postmanlabs/postject/pull/24 landed, we started building and testing on the linux executor, so there's no need to use the alpine and debian executors anymore.

@RaisinTen Can you mention the reason behind reducing the test matrix? I understand the reduction of build matrix, as we are not packaging postject differently on different executors.

[RaisinTen]

Same reason as the build matrix. I don't see the reason why we are running tests on alpine and debian when linux seems to be enough.

@RaisinTen as explained before in #24, I originally designed the matrix to have a broader coverage like this

while implementing linux support, I could've chosen to use glibc helpers for implementing the runtime access, but did not in favour of being able to support musl. having tests on both that ensure this continues to be the case was the main driver for testing on debian and alpine

I don't think postject should limit itself to the platforms covered by starship

[RaisinTen]

@robertgzr Ah so it's about musl, that sounds reasonable. Which one of debian and alpine uses musl?

[RaisinTen]

I don't think postject should limit itself to the platforms covered by starship

The thing is that starship is currently the only user of postject. Maybe we can add support for other platforms on need basis when we have users there?

I agree with @robertgzr here.

We want the project to be generic and forward looking, I don't see much of a downside to testing on more platforms. Either the tests pass and all is good, or they don't and there's something we should fix to keep the project working on as many platforms as possible.

Yes, I'm fully supportive of that idea!

I don't see much of a downside to testing on more platforms.

But there is no upside either if there are no users of Postject on such platforms.

The benefit is we have test coverage and know it works on these platforms, we don't want to wait until there are users for those platforms to find out if they work. 🙂

During the discussion in the Starship meeting I learnt that alpine, which is musl-based is significantly popular. I didn't consider that while sending this PR, so I'll remove the alpine related changes. But how about the debian part? How popular is that w.r.t linux and alpine @robertgzr?
