Tailwind preset is not compatible with Theme TypeScript type

[schickling]

Describe the bug

The Tailwind preset is not compatible with Theme TypeScript type.

To Reproduce
Steps to reproduce the behavior:

1. Copy & paste the JSON theme definition and assign it to a variable with type Theme (via import { Theme } from 'theme-ui')
2. Watch out for type errors (Note: There are more TypeScript errors once you've fixed/commented out the initially reported errors)

Here is a repo on CSB: https://codesandbox.io/s/repro-theme-ui-tailwind-typescript-olnsp

Expected behavior

The presets should be compatible with the Theme type.

Hi, @schickling

Can you please try https://github.com/atanasster/theme-ui/blob/tailwind-preset-typescript/packages/preset-tailwind/src/index.ts

If it looks good, we can submit it as a PR.

@hasparus - I suspect most other themes will also need to be updated. New themes created will probably use those as templates.

This should be fixed between those PRs & #1862!
