[Issue] Optimize devcontainer Dockerfiles

[jongio]

We are using --platform=amd64, which shouldn't be needed anymore. Please test on Apple Silicon after removing because that would be the reason to have that flag, as it was crashing w/o it.

Also, let's investigate if we can use language specific base containers instead of the /base container.

i.e. mcr.microsoft.com/devcontainers/python:3.9

instead of mcr.microsoft.com/devcontainers/base

And do that for every lang.

For the node projects use the node base, .net/.net, etc.

Re --platform=amd64, is that not needed anymore with the current azd release or future ones? (I can test on my M1 if its in current release).

[jongio]

It's not azd dependent, so you can remove now and test. (If you feel like helped that is :))

Hm, when I remove it, I get a failure on what looks like the install-azd stage:

 => ERROR [dev_container_auto_added_stage_label 2/2] RUN curl -fsSL https  2.3s

It works when I put it back.

My file-

ARG VARIANT=bullseye

@pamelafox can you try with the internal ARM64 bits which was shared and give us feedback?

[rajeshkamal5050]

@danieljurek assuming that this depends on #1314 moving to Gallium. Please adjust, if otherwise.

[danieljurek]

Dependency is correct. Until we're publishing ARM64 binaries for Linux the Linux devcontainers will need to run in amd64 emulation mode when running on ARM64 hosts.
