Ubuntu 22.04 container image

[kyleconroy]

Workflows currently supports ubuntu-18.04 and ubuntu-20.04. Would it be possible to add a ubuntu-22.04 image as well? We're running into an issue where a set of rules we use needs a newer version of curl than the one 20.04 provides.

actions:
  - name: "Test all targets"
    container_image: "ubuntu-20.04"
    triggers:
      push:
        branches:
          - "main" # <-- replace "main" with your main branch name
      pull_request:
        branches:
          - "*"
    user: "buildbuddy"
    bazel_commands:
      - "test //..."

Hey Kyle, we definitely want to do this, but supporting new workflow images comes with a few performance-related challenges for us at the moment that we are working to sort out first. We'll keep this issue updated with progress 👍
