fix(ts): export types explicitly

[pavelfeldman]

Fixes #14348

[yury-s]

Please add a test for this.

I won't need a test once we move to TS 4.7. We have the opposite problem though, we might need bots for earlier versions of TS.

any chance for a bugfix release with this change? just noticed it didn't resolve types in native esm mode (node16 module/moduleResolution)... 😮

was going to report it using the following reproduction steps:

mkdir playwright-node16-bug
cd playwright-node16-bug
npm init -y
npm i playwright-core typescript -D
npx tsc --init --module node16 --moduleResolution node16
echo "import playwright from 'playwright-core'; console.log(playwright);" > bug.mts
npx tsc

@AviVahl you can use the next version npm install playwright-core@next!

thanks for the tip. 👍 would be useful in own projects, but my team is using some dependencies with stable playwright peerDeps.

I'm currently using "module": "esnext", "moduleResolution": "node", but wanted to switch to "node16", as it actually works as I'd expect (picks up "exports").
