[fix][test] Update OpenTelemetry receiver endpoint in integration test

[dragosvictor]

Fixes #22995

Motivation

OpenTelemetry integration tests are broken due to an upstream change in the OTel receiver. The receiver had a breaking change in v0.104.0, where the listener binds to localhost unless otherwise instructed (ref).

Modifications

Bind the receiver to 0.0.0.0:4317 for the integration tests.
