Adds ".mts" and ".cts" extensions to the known/defaults list
See the esbuild@0.13.4 release notes for more information. Even though these notes are primarily esbuild.build-oriented (tsm uses esbuild.transform), bumping the esbuild version for full cts/mts support is the preferred, coherent solution.
