Zipkin: Run health check through backend (#96031)

* Zipkin: Run health check through backend

* Mark some errors as downstream

* Update pkg/tsdb/zipkin/zipkin.go

Co-authored-by: Will Browne <wbrowne@users.noreply.github.com>

* Use errors.New where error formatting is not needed

* Remove executable in plugin.json

* Fix joining the path

* Keep logger as global and then create from context

* Close the res body

---------
