fix: README generation

Changed from trying to use artifacts and the GHA workflow failing to now using a simple `BUILD_VERSION` repository variable and automatically updating that when the `build-and-push-to-registries` workflow succeeds.

Other changes include:

* Added `workflow_run` trigger to `generate-readme.yml` so when that workflow recognizes the “Publish Docker Image to Registries” workflow runs and succeeds, it will automatically run the `generate-readme.yml` workflow (since a new Docker release will require Docker image variants table in README.md to have versioning updated)
* Generate major and major-minor versions from the `BUILD_VERSION` repository variable (more efficient than storing three separate variables from the `build-and-push-to-registries` workflow job)
