fix: check for nonempty kv id and r2 bucket_name

[arjunyel]

Close #1660

In packages/wrangler/src/config/validation.ts I originally tried to get isRequiredProperty to type narrow object. This may be impossible microsoft/TypeScript#31755 (comment) so I casted it manually.

Looks good to me. Thank you for the PR!
