Description

I want to use TypeScript with a .mjs (module) Gulpfile. So I renamed my gulpfile to gulpfile.mts, but it says No gulpfile found. TypeScript says it supports the .mts extension here. The above applies to gulpfile.esm.ts and gulpfile.babel.mts and gulpfile.babel.mjs too.

Research direction
Investigate how gulp currently resolves gulpfile names, specifically in the 'interpret' package or the main gulp cli logic. Look for file extension patterns and add '.mts' to the list of supported extensions. Also check if TypeScript compilation is handled for .mts files. Refer to the Node.js documentation for .mts support.
