fix: add types condition to the front of the exports

[Andarist]

Reopening mysticatea#30 here as suggested by @MichaelDeBoey

I added types condition to the front. package.json#exports are order-sensitive - they are always matched from the top to the bottom. When a match is found then it should be used and no further matching should occur.

Right now, the current setup works in TypeScript but it's considered a bug and it should not be relied upon, see the thread and the comment here. For that reason, I would like to fix all popular packages that misconfigured their exports this way so the bug can be fixed in TypeScript.

⚠️ note that this doesn't fix all of the types-related problems in this package (see the reported problems here). This PR only focuses on "🐛 Used fallback condition" because that's a TypeScript bug that can't be fixed before the usage gets fixed in popular packages.
