Set default Record types to string

[Konrad Pettersson]

When using the the TypeScript Record utility type, the vast majority of times, at least in my experience, the key is of type string.
So why is it not the default?
I propose that string should be the default type for both parameters,
and when only one argument is provided, is should be the type of the value,

My proposition	Current behavior
Record<>	Record<string, string>
Record<Animal>	Record<string, Animal>
Record<number, Animal>	Record<number, Animal>

Don't think we can make this work, given that Record is specified with a type and ts-reset works via declaration merging.
