fix: change startIndex option type from string to number

[arjunmehta]

startIndex should be an 0-indexed integer. But as it is was expecting a string which is incorrect and caused a lot of confusion, preventing compilation and requiring odd workarounds.

this file should not be manually modified, as it is generated from the Discovery doc (with the command npm run types).

@alvarowolfx Ah got it, I will close this PR then but the issue remains open. I am happy to contribute a solution, but not sure where to find/update the relevant Discovery Doc definition. If you want to point me to it I can attempt. Or someone who knows the procedure might be better suited to make the quick fix.

the Discovery document represents the backend/API definition, so it can only be changed by the service side itself. In this case, would be a change on the BigQuery backend.

What can be done is to change the generated code to take into consideration the format field of the Discovery doc, not just the type field. But in the end what the service side accepts is a string, so some conversion would have to happen.

Another thing to consider is that the startIndex attribute expects an uint64 and that can't be represented with a integer in Javascript, which holds at most 2^53 - 1. So users would have to use a BigInt and convert to string anyway.
