Feature (Development): Create Devcontainer

[chtzvt]

It'd be nice to centralize the local development environment setup/configuration into a devcontainer.

I am abandoning this for now.

• Performance in the devcontainer is extremely slow for me.
  • Basic actions (such as loading the login page) can be fast, or they can take more than 20 seconds. It's not consistent.
  • This is not only because of disk performance [1], but also due to my use of an M1 Macbook, which has to run the app container's amd64 image in emulation via Rosetta.
  • The reason I have to use an amd64 container image is particularly because Google Chrome is not packaged for aarch64 on Linux, and without Chrome, the full test suite cannot be run.
  • Also because of the amd64 emulation above, native extensions are spontaneously segfaulting.

The bottom line: There are tons of benefits to using devcontainers, but right now my experience has been slow, flaky, and inconsistent for this particular application.

I'm leaving the devcontainer branch up with all of the relevant configuration for us to return to this later, or if other developers would like to take a crack at optimizing it further.
