Improved devcontainer setup with e2e test mini infra

[solnic]

This reworks our devcontainer setup so that it uses pre-built base images grabbed from ghcr.io and enables running e2e tests easily both on CI and locally.

There's a top level setup now in the root dir under spec where we can write high-level cross-gem e2e tests.

This is a solid foundation for building even more conveniences around development/debugging/testing in the future 🙂

To run e2e tests locally you can simply do:

cd .devcontainer
docker compose run --rm sentry-test bundle exec rake

I tried running it on mac and linux both, neither works. We need to make this work without vscode since I do not use it.

On linux, the error is
