[SPARK-57774][CORE] DriverLogger should not propagate log4j internal exception to caller

### What changes were proposed in this pull request?

Flip the `setIgnoreExceptions` from false to true in `DriverLogger`

### Why are the changes needed?

https://logging.apache.org/log4j/2.x/plugin-reference.html

> ignoreExceptions - If "true" (default) exceptions encountered when appending events are logged; otherwise they are propagated to the caller.

The recent log4j 2.25.0 ~ 2.25.3 and 2.26.0 have [known internal bugs](#51719 (comment)) and may fail the Spark caller, this has been observed from the GHA several times.
