Use OPTIONS for sliding sync detection poke (#12492)
* Use OPTIONS for sliding sync detection poke

This avoids unintended consequences, including high resource usage, which would accompany a "full" sync request. Instead, we just grab headers and enough information for CORS to pass, revealing likely support.

Fixes https://github.com/element-hq/element-web/issues/27426

* Appease the linter

* Reset for each test
