Describe the bug

e.g. when using z.record(z.any()) as output validator, the inferred type on the client is {}.

Actual:

type Baz = Serialize<Record<string, any>>; // {}

Expected:

type Baz = Serialize<Record<string, any>>; // Record<string, any>, or { [x: string]: any; }

To reproduce

Paste the bug description into packages/server/src/shared/internal/serialize.ts

Additional information

Serialize<Record<symbol, string>> also gets inferred as { [x: symbol]: string } which is incorrect. Perhaps that would be a separate issue to file, but I think multiple of these bugs related to Serialize<Record<...>> can probably be fixed in one go.
