Systems that aggregate logs like Sentry will group all captured warnings under the same event which makes it difficult to assess common warnings

Could you give an example of the problem?

Of course, here's an example script to reproduce:

```
import logging
import warnings

import sentry_sdk
from sentry_sdk.integrations.logging import LoggingIntegration

logging.captureWarnings(True)

sentry_logging = LoggingIntegration(
    level=logging.INFO,
    event_level=logging.WARNING
)

sentry_sdk.init(
    "<ingest URL>",
    traces_sample_rate=1.0,
    integrations=[
        LoggingIntegration(
            level=logging.INFO,
            event_level=logging.WARNING
        )
    ]
)

warnings.warn("A warning")
warnings.warn("Another warning")
```

I attached a file of what it looks like in the Sentry UI. Notice both warnings under the same issue. When logging warnings directly with the logging module, each message arrives as a separate issue. These warnings from the warnings module are both grouped together under the same issue since Sentry groups all logs with the same format string together.
