chore: exports condition add `types`

[Gehbt]

Config "modeResolution": "bundler" will read exports condiction types to get type

[danielroe]

If it is omitted, it will look for ./dist/module.d.mts for import and, ./dist/module.d.cts for require.

Are you opening this PR because you are encountering an issue?

The first problem I find is from nuxt-monaco-editor, and I search the solve at nuxt/sitemap or nuxt-modules/tailwindcss with issue

Sometime, the module haven't module.d.mts or module.d.cts but typically includes types.d.ts. if someone want register config to @nuxt/schema, he should set this. If it is as a convention.
