subscriber: update tracing-core to v0.1.33 (tokio-rs#3201)

The change tokio-rs#2954 was released in 0.3.19 (tokio-rs#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 tokio-rs#2945, or [ `impl
field::Visit for
JsonVisitor<'_>`](https://github.com/tokio-rs/tracing/blame/master/tracing-subscriber/src/fmt/format/json.rs#L491))

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.
