[feat] Add GQL mutation to store event metrics

[rohitvinnakota-codecov]

Purpose/Motivation

This PR closes codecov/engineering-team#1829

Adds a GQL mutation that will exclusively be used by gazebo to track page visits and button clicks for onboarding metrics. This setup is designed to fail silently and interfere with the regular flow as little as possible.

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.

looks good, just the minor stuff with event vs event_name, potentially typing event from str -> event enum
