Which issue does this PR close?

N/A - minor diff consistency fix.

Rationale for this change

The filter pushdown - StringPredicate test in the 3.4.3 Spark SQL test diff uses IgnoreCometNativeDataFusion while the same test in the 3.5.8 and 4.0.1 diffs uses IgnoreCometNativeScan. The test fails because the native scan doesn't propagate the NumRowGroupsAcc Spark accumulator, so IgnoreCometNativeScan is the more appropriate tag.

What changes are included in this PR?

Changed the tag on the "filter pushdown - StringPredicate" test in dev/diffs/3.4.3.diff from IgnoreCometNativeDataFusion to IgnoreCometNativeScan for consistency with the other Spark version diffs.

How are these changes tested?

Verified the test still fails with COMET_PARQUET_SCAN_IMPL=native_datafusion (accumulator returns 0), confirming the ignore tag is still needed. The change only narrows the scope of the ignore to match the other diffs.

Change the tag on "filter pushdown - StringPredicate" test from
IgnoreCometNativeDataFusion to IgnoreCometNativeScan for consistency
with the 3.5.8 and 4.0.1 diffs.
