[Feature] Global query parameters in Fern Definitions

[minaelee]

Fern Definitions currently support global path parameters, but not global query parameters as of yet. This means the ability to specify query parameters that are meant to be included on every request. If you would like this feature to be added, please upvote this issue.

See: https://docs.buildwithfern.com/api-definition/fern-definition/api-yml-reference#global-query-parameters

+1 from me. We have the same query parameters copy-pasted all over our fern definitions
