Add .mts and .cts config file detection

[RobinMalfait]

This PR will add support for detecting tailwind.config.cts and tailwind.config.mts files by default.

This PR will also remove some warnings that Node v22 was showing in the terminal when using ESM files (or TS files). If you happen to use an ESM file (.mjs) or any TS file (.ts, .cts or .mts), then we will immediately use jiti instead of first trying to require the file. Requiring these files triggers Node in logging the warning.

Fixes: #13927

We should probably add tests for these proving .mts and .cts config files work. e.g.

tailwindcss/integrations/tailwindcss-cli/tests/integration.test.js
