feat: add tailwind support

[Yordan-Ramchev]

Hi @sodatea @cexbrayat,

I've opened a pull request(re #246) that introduces:

1. Introduced Tailwind prompt functionality with an untranslated prompt message.
2. Ensured compatibility for both JavaScript (js) and TypeScript (ts) scenarios.
3. Modified generateReadme.ts for necessary updates.
4. Incorporated the Tailwind feature flag into snapshot.mjs.

I would appreciate your time and expertise in reviewing these changes.

Thank you!

One concern is that the approach at https://github.com/vuejs/create-vue-templates is n! on the number of options. Probably also the CI matrices? There's already a lot of directories in that repo, and over 100 CI checks... at what point will that approach break down?

I recognize that this is not about your code itself, but about the practicalities of maintaining all combinations of options.

At a minimum, you probably need to add the tailwind option to https://github.com/vuejs/create-vue/blob/main/.github/workflows/ci.yml

@bmulholland thank you for the feedback. I have added tailwind flag in CI and that's (n! on the number of options) a reasonable concern

Note: this PR is a duplicate of an older PR #245 If one of the two is merged, the other can be closed.

I personally don't think it's worth the added complexity to add tailwind support, but I'll let @sodatea decide.
