fix: change the empty object type {} to use TS Record utility type

[aniravi24]

To use the more accurate type based on typescript/eslint's recommendations, The generated type when there's no param was changed to Record<string, never>

 Don't use `{}` as a type. `{}` actually means "any non-nullish value".
- If you want a type meaning "any object", you probably want `Record<string, unknown>` instead.
- If you want a type meaning "any value", you probably want `unknown` instead.
- If you want a type meaning "empty object", you probably want `Record<string, never>` instead

For example, this is valid in the current main branch

But once it's changed, now it throws an error

However, this is still valid as expected

@sandulat we enabled a plugin in our project that triggered this error, thought I should change it here so it works for everyone! The Record utility type has been around since TS 2.1 so it should work.
