🐛🔧 Add "types" to "exports"

[makeeno]

When trying to use fast-check with TypeScript where moduleResolution is set to Node12 or NodeNext we get the following error:

Could not find a declaration file for module 'fast-check'. '.../node_modules/fast-check/lib/esm/fast-check.js' implicitly has an 'any' type.
Try npm i --save-dev @types/fast-check if it exists or add a new declaration (.d.ts) file containing declare module 'fast-check';ts(7016)

This change fixes the issue.

I think this might be related: microsoft/TypeScript#46334

Thank you so much for the fix @Osman-Sodefa! I'll probably need to cover it as I did for other esm-related stuff in https://github.com/dubzzz/fast-check/tree/main/test/esm.

Is there a specific version you need the fix in? I mean which version do you need to include the fix?

No specific version. I'm currently using the latest of fast-check. Thank you.

2.23.1 is on its way 🚀

I'll probably need to cover it as I did for other esm-related stuff in https://github.com/dubzzz/fast-check/tree/main/test/esm.

Though I think it's more TS related than ESM related.

[dubzzz]

I mean I put all the environment related issues into this directory. It's probably not well labeled 😂

[dubzzz]

It will probably not work yet! I'll need to do the exact same fix for pure-rand 🤔

See the error I got when trying to add a dedicated test:

Error: node_modules/fast-check/lib/types/random/generator/PureRandom.d.ts(1,60): error TS7016: Could not find a declaration file for module 'pure-rand'. '/home/runner/work/fast-check/fast-check/test/type/node_modules/fast-check/node_modules/pure-rand/lib/pure-rand.js' implicitly has an 'any' type.
  Try `npm i --save-dev @types/pure-rand` if it exists or add a new declaration (.d.ts) file containing `declare module 'pure-rand';`
Error: Process completed with exit code 2.

I have enabled skipLibCheck in my tsconfig.json; that's why I didn't get that error.

[dubzzz]

I'll update it on my side so that the whole fast-check + pure-rand gets fixed! Thanks a lot for the report and the fix!
