Fix typesVersions path mapping

[hasali19]

Thanks for this awesome library!

I've been running into an issue where vscode adds auto-imports like import { css } from 'solid-styled/*' instead of import { css } from 'solid-styled'. This change seems to fix it.

Sorry about that. Yeah I discovered the root of the issue (which is the missing types field), however overwriting typesVersion won't be able to fix it alone since that field is automatically generated. Fear not, I've already fixed it on the bundler-side so I'll push a hotfix immediately. I'll merge this as part of the contribution, thanks!
