Export typings from package.json

[aleksandrjet]

When I try to export preact-ssr-prepass to an application using nodeJs^18 I get an error:

Could not find a declaration file for module 'preact-ssr-prepass'. 
'.../node_modules/preact-ssr-prepass/dist/index.mjs' implicitly has an 'any' type.
There are types at '.../node_modules/preact-ssr-prepass/typings/index.d.ts', 
but this result could not be resolved when respecting package.json "exports". 
The 'preact-ssr-prepass' library may need to update its package.json or typings.

This happens because nodeJs^18 firstly looks at the exports field in package.json, but the types are not specified there.

Description of main field:

The "main" field defines the entry point of a package when imported by name via a node_modules lookup. Its value is a path. When a package has an "exports" field, this will take precedence over the "main" field when importing the package by name.

For what it's worth, this isn't Node -- Node never has (or likely will) care about the "types" condition. This is from TS under specific "moduleResolution" settings.
