Enable Bicep linting support in the github / super-linter project

I'm using the github / super-linter (Docker image in a CI/CD pipeline) to lint multiple file types (json, yaml, etc.) and would like to see it include linting support for Bicep linting. I've created a related issue over in that project's Issue list: https://github.com/github/super-linter/issues/1610

The request targets github/super-linter rather than a named file in this repository; start by reviewing the related issue at github/super-linter#1610 and its current status. Confirm the integration needed for Bicep linting in the Docker-based CI/CD workflow; done means the super-linter can run Bicep checks alongside the other requested file types.
