optional flag to use commonjs configuration when installing

[emerson-argueta]

When installing tailwind using this gem the command is bin/rails tailwindcss:install
Using this command adds necessary configuration files to a rails project.
One of these configuration files is tailwind.config.js
I see there is no option to use a commonjs config file instead.
It would be nice to give an optional flag for the install command such as --config-ext=commonjs to add and use the tailwind.config.cjs file instead.
The commands then would look like this:
bin/rails tailwindcss:install --config-ext=commonjs
bin/rails tailwindcss:build --config-ext=commonjs
bin/rails tailwindcss:watch --config-ext=commonjs

One of the reasons I raise this issue is because the current tailwind.config.js conflicts when using packages that are ESM modules in my project.

For example my package.json needs to have "type":"module" for vite and svelte to work together in my rails project.

There might be another solution to solve my problem.
However, I have forked this repo made some changes and created my own version of this gem which only uses the commonjs configuration and it worked.

I know adding this optional flag would require adding the tailwind.config.cjs in the repo and some changes across different files.
I can create a pull request for this, but wanted to know before doing that if this should be implemented.
