Currently LeakCanary is still using Travis CI for PR checks.

We should migrate to GitHub actions, including for UI tests.

Some examples we can look at, which I think @zach-klippenstein took care of:

https://github.com/square/workflow-kotlin/

When entering a repository path, users should be able to hit TAB for autocomplete, like in bash.

{
  "$schema": "http://json-schema.org/draft-07/schema#",
  "$ref": "#/definitions/foo",
  "definitions": {
    "foo": {
      "type": "object",
      "properties": {
        "bar": {
          "$ref": "bar.json#"
        },
      },
      "required": [
        "bar"
      ],
    },
    "title": "foo"
  }
}

Running quicktype CLI with this Schema produces
