w3c tracecontext testcontainers test seems to have ability to freeze CI

No leads but it seems these tests aren't stable on CI right now so will disable for now (they're most useful locally anyways)

@anuraaga I don't think we've seen this type of issue in a while. Is it still relevant?

[anuraaga]

The tests aren't enabled by default still, it would be good to do that if possible though
