Ignore a deprecation warning from sentry_sdk

As of its [2.21.0
release](https://github.com/getsentry/sentry-python/releases/tag/2.21.0)
`sentry_sdk`'s Celery integration has begun emitting this deprecation
warning:

    E       DeprecationWarning: The `propagate_traces` parameter is deprecated. Please use `trace_propagation_targets` instead.

    .tox/tests/lib/python3.12/site-packages/sentry_sdk/integrations/celery/__init__.py:73: DeprecationWarning

h-pyramid-sentry doesn't actually use the `propagate_traces` parameter.
In fact all it's doing is inititalising `sentry_sdk`'s Celery
integration with no arguments:

    from sentry_sdk.integrations.celery import CeleryIntegration

    init_options["integrations"].append(CeleryIntegration())

https://github.com/hypothesis/h-pyramid-sentry/blob/6de9124faa29ca99979bc08318af7c45e0487586/src/h_pyramid_sentry/__init__.py#L54-L56

`sentry_sdk` appears to emit the warning unconditionally whenever anyone
uses the Celery integration:

    class CeleryIntegration(Integration):
        identifier = "celery"
        origin = f"auto.queue.{identifier}"

        def __init__(
            self,
            propagate_traces=True,
            monitor_beat_tasks=False,
            exclude_beat_tasks=None,
        ):
            # type: (bool, bool, Optional[List[str]]) -> None
            warnings.warn(
                "The `propagate_traces` parameter is deprecated. Please use `trace_propagation_targets` instead.",
                DeprecationWarning,
                stacklevel=2,
            )

https://github.com/getsentry/sentry-python/blob/25ddbcad9642cf38b7a9668e348f80fb9b1c892e/sentry_sdk/integrations/celery/__init__.py#L62-L77

The warning was added by this PR: getsentry/sentry-python#3899.

Just ignore the warning, as there's no way for us to fix this.
