Allow pageParam to be a string within generated infiniteQueries

[robert-pitt-foodhub]

Describe the bug
Our API uses string as page parameters, such as base64 encoded global ids, however when generating infinite queries where the type of pageParam is not a number within the schema

To Reproduce

1. Generate schemas where the page types are strings using openapi-rq --pageParam nextPageKey --nextPageParam nextPageKey -i specification.json -c axios
2. See the generated queries/infiniteQueries.ts file for type error

OpenAPI spec file
Would like to keep private

Expected behavior
If the schema defines the page token as a string then the generated types should also require a string.
