Queries with array parameters doesn't work

[Alexander]

Describe the bug
Queries with query parameters that are array based doesn't work.

It boils down to this line:

openapi-to-graphql/packages/openapi-to-graphql/src/resolver_builder.ts

Line 1374 in 8951518

 if (param.style === 'form' && typeof args[saneParamName] === 'object') { 

An array is also considered an object in JavaScript. The if statement needs to be flipped.

The queryString parts of that library should probably be handled by https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams as well.
