fix(types): export all types as "type" to avoid exporting in .js (#4837)

* fix(types): export all types as "type" to avoid exporting in .js

This issue is caused by `export * from './types'` added in #4834, which causes everything in /types to be exposed, but unfortunately because `export from` in the InstantSearch file mixed a type and a value, and thus exported it.

This is done by enabling [consistent-type-imports](https://github.com/typescript-eslint/typescript-eslint/blob/master/packages/eslint-plugin/docs/rules/consistent-type-imports.md) in eslint to make sure it's correct in all cases

- vite reproduction: https://github.com/eunjae-lee/vue-instantsearch-with-vue3-and-vite

* fix ts

* chore(ts): also enable `isolatedModules`

this catches when you export something that's a type as a regular export, further avoiding the issue
