fix: change package.json to resolve the type definition file when moduleResolution: bundler is defined in tsconfig.json

[3846masa]

When moduleResolution: bundler is defined in tsconfig.json, TypeScript finds the type definition from exports fields in package.json.

However, exports fields has no types fields, TypeScript cannot search the type definition.

This PR changes package.json to resolve the type definition when moduleResolution: bundler is defined in tsconfig.json.
