Feature Request: Add support for .mts configuration files

[jscarle]

In an issue originally identified in the TailwindCSS repository, I've been able to work through the upstream dependencies and found that vite relies on postcss-load-config to load it's configuration files. So I'd like to ask that support be added for .mts files so it can be integrated downstream.

tailwindlabs/tailwindcss#13927

What build tool (or framework if it abstracts the build tool) are you using?

vue 3.4.31, typescript 5.5.2, vue-tsc 2.0.24, vite 5.3.2, tailwindcss 3.4.4

Nevermind, I just realised it's already integrated, vite is simply using an older version.
