Subject: [PATCH] Update action to use prebuilt Docker image

Update the action to use a prebuilt Docker image and add workflows for continuous delivery and version checking.

* **action.yml**
  - Update the `runs` section to use `ghcr.io/launchdarkly/find-code-references-in-pull-request:latest` as the prebuilt Docker image.

* **.github/workflows/main.yml**
  - Update the `Find LaunchDarkly feature flags in diff` step to use the prebuilt Docker image `ghcr.io/launchdarkly/find-code-references-in-pull-request:latest`.

* **.github/workflows/cd.yml**
  - Add a new workflow to build and publish the Docker image based on the example from `container-prebuilt-action`.

* **.github/workflows/version-check.yml**
  - Add a new workflow to check the version of the Docker image based on the example from `container-prebuilt-action`.

* **Dockerfile**
  - Delete the Dockerfile as it is no longer needed.
