chore(requests): fix local test runs (#10769)

Running requests tests locally results in httpbin connection errors.
This regression was introduced in
72f4032#diff-9885ff9747de8410ef5d9849c7c0950e34f9a2b86bf340d5a05fa2d1514854bb.
This PR ensures the service alias used in gitlab is consistent with the
service name used in docker-compose. This change ensures requests tests
pass both in gitlab and locally.
