[Defend Workflows] Adjust headers in fleet api

[tomsonpl]

• Adjusting api/fleet usage after [Fleet] Introduce API versioning for serverless #163570 being merged.
• Added Osquery Cypress tests to the Pipeline if changes are done in Fleet directory

Worth to mention that Osquery tests found some missing pieces in api/fleet (missing version).

Combined work of @szwarckonrad @gergoabraham @ashokaditya - thanks!

I've two suggestions.

1. use consistent lowercase elastic-api-version everywhere
2. move headers key to the top of every request object, so

 request( headers, method, path, body)

LGTM, thanks for fixing the missing versions in Fleet!
