`npx convex function-spec` crashes on literal BigInt

[dickermoshe]

Running npx convex function-spec on an environment which has the following function crashes:

export const query12 = query({
  args: {
    i: v.literal(BigInt(1)),
  },
  returns: {
    i: v.literal(BigInt(1)),
  },
  handler: (ctx, args) => {
    return args;
  },
});

Results in the following crash:

Error: [CONVEX Q(_system/cli/modules:apiSpec)] [Request ID: 4720b13eabb84ec5] Server Error
Uncaught Error: Field name $integer starts with a '$', which is reserved.

This was caught during testing of a dart client I'm working on.
Discovering a bug in convex itself was very unexpected.

Yep! This is a bug.
