Allow non-AMD64 devcontainer, such as ARM (reverts #3328)

[evnchn]

Motivation

I just checked and we can install chromium and chromium-driver on ARM64, covering a major use case of developing on Apple Silicon Macs

I can't trace back which release it was supported, though.

So we can revert #3328 and improve devcontainer performance.

For those who need AMD64 they can specify it themselves?

Implementation

Revert #3328, drop --platform=linux/amd64

Progress

• I chose a meaningful title that completes the sentence: "If applied, this PR will..."
• The implementation is complete.
• Pytests are not necessary.
• Documentation is not necessary.

I'm still on the ARM64 devcontainer, by the way.

Tests cannot run??

🤡

I don't have that much experience. Let's make this draft until someone can look at this and make the tests pass, so that we don't accidentally merge this and mess up the devcontainer for everybody.

Don't ask me why but with e2c6ba9 it works

Not all tests pass though, some fail, but I don't know why. The tests which do pass though, they are very fast.

I just realized that actually for Polars it will complain if you use AMD64 devcontainer on Apple Silicon

https://github.com/pola-rs/polars/blob/afdbf3056d1228cf493901e45f536b0905cec8ea/py-polars/src/polars/_cpu_check.py#L250-L262

So for Apple Silicon Macs, this PR is more important than what it seems.
