Subject: [PATCH] Update `supertest` and `superagent` to latest version
 (#183587)

## Summary

Related to https://github.com/elastic/kibana/issues/7104

Update supertest, superagent, and the corresponding type package, to
their latest version.

(of course, types had some signature changes and we're massively using
supertest in all our FTR suites so the whole Kibana multiverse has to
review it)
