Remove WebauthnStimulusExtension and refactor WebauthnStimulusBundle

This commit removes the WebauthnStimulusExtension file as it is no longer necessary. Instead, the necessary methods to check AssetMapperAvailability and prepend extensions have been moved to the WebauthnStimulusBundle file. This refactoring simplifies our codebase by reducing redundant components and enhancing the readability of the code.
