fix: Remove devcontainer folder when .codesandbox/Dockerfile identified (#196)

* When building a template we should identify if there is a .codesandbox/Dockerfile in the template, if so during writing of files to the Sandbox we should also delete the .devcontainer file already in the Sandbox. This is related to the CLI build command

* chore: clean up
