writeOutput method
Formats and writes the generated content to the output file.
Attempts to format the content using the configured formatter. If formatting fails, logs an error but proceeds with writing the unformatted content. In development mode, allows syntax errors in the generated code.
@param buildStep The build step to use for writing @param content The content to format and write @param extension The file extension to use for the output
