Clarify docs for getting tailwind config file

[nrgnrg]

In more custom setups the tailwind config file might not be in the project root or might be named differently to tailwind.js or tailwind.config.js.

Tailwind supports these setups by specifying the config file in postcss.config.js

for example

module.exports = {
  plugins: {
    tailwindcss: { config: "./tailwind.config.cjs" },
    autoprefixer: {},
  },
};

It would be good if this plugin could scan postcss.config.js and if the tailwind file is defined there use that.

This actually appears to work so perhaps a clarification in the docs is needed?

Yep tailwind.config.cjs is supported! Added a clarification to the readme, thanks!
