ref: Fix GQL casing inconsistency throughout API

[ajay-sentry]

Purpose/Motivation

The default object case behavior is deprecated: snake case fallback resolver
Ariadne calls out convert_names_case as the new correct way to convert case names

This PR aims to update all the inconsistencies throughout API and consequently, this also means we can remove all the instances of @convert_kwargs_to_snake_case in a followup!

What does this PR do?

PR updates all the camelCasing throughout the graphQL layer to snake_casing since we get it for free now with the new schema option

Legal Boilerplate

Look, I get it. The entity doing business as "Sentry" was incorporated in the State of Delaware in 2015 as Functional Software, Inc. In 2022 this entity acquired Codecov and as result Sentry is going to need some rights from me in order to utilize my contributions in this PR. So here's the deal: I retain all rights, title and interest in and to my contributions, and by keeping this boilerplate intact I confirm that Sentry can use, modify, copy, and redistribute my contributions, under Sentry's choice of terms.
