tracing-subscriber: bump tracing-core to 0.1.33

[nkconnor]

#2954 was released in 0.3.19 #3162

Notably, it relied on features from tracing-core 0.1.33, however, the version was never bumped. Users of the tracing feature of tracing-subscriber would have no issue since it pulls in the higher version transitively.

The specific feature used was implementing trait method record_bytes from the field::Visit trait on JsonVisitor from the tracing-subscriber json format module. (see linked #2945, or impl field::Visit for JsonVisitor<'_>)

I believe this dependency mismatch requires users to manually select the higher tracing-core version or suffer compilation failure.

This probably reflects some failure in how the tests utilize features and intra-workspace dependencies, but, a resolution for that is beyond my current comprehension of the project.
