fix: replace temporalio[opentelemetry] extra with explicit opentelemetry deps

Using the opentelemetry extra on the temporalio specifier caused uv to
resolve a different dependency graph in tutorial environments (uv run
--with wheel), which broke the _JSONTypeConverterUnhandled import used
by scale-gp at worker startup time.

Listing opentelemetry-api and opentelemetry-sdk as explicit direct
dependencies keeps the same packages in the wheel while letting
temporalio resolve independently in tutorial envs — matching the
pre-existing resolution that scale-gp expects.
