Add an `ignore_loggers` kwarg to `LoggingIntegration`

### Problem Statement

It's simply more convenient to have a kwarg for this, instead of having to call `ignore_logger()` multiple times 🙂

### Solution Brainstorm

```python
class LoggingIntegration(Integration):
def __init__(
self,
...,
ignore_loggers=None,
):
...
# --- Either: ---
for logger in ignore_loggers or ():
ignore_logger(logger)
# --- Or: ---
_IGNORED_LOGGERS.update(ignore_loggers or ())
```

Start by locating LoggingIntegration and the existing ignore_logger() entry point, then inspect how _IGNORED_LOGGERS is maintained. Decide which proposed initialization path matches the surrounding design. Done means LoggingIntegration accepts ignore_loggers and registers each supplied logger without changing existing ignore_logger() behavior; run the relevant integration tests if available.
