test(quantic): ep analytics tests fixed in the e2e (#4529)

## [SFINT-5732](https://coveord.atlassian.net/browse/SFINT-5732)

## Changes made in this PR:

### In Headless:

1. Fixed a typo in type of the event sent when submiting feedback for
RGA, it's now `Rga.SubmitFeedback` instead of `Rga.SubmitRgaFeedback`.

### In Quantic: 

- Fixed all the E2E tests that were previously skipped because of the
latest breaking changes that occurs to schemas of the EP events, in this
tests we check that the right payload is sent and that each analytics
call is valid by sending it to the `validate` endpoint of the Event api.
