Workaround NI on MacOS issues with NaN formatting (#14572)

`DecimalFormat` suddenly decided to format Double.NaN
as `U+FFFD REPLACEMENT CHARACTER` (or `?`) on MacOS in NI mode.
There were no changes to the underlying code or configs so it's a bit of
a mystery why it started now when it worked before.

Setting explicitly the name in `DecimalFormatSymbols` does the job,
because modifying reflection configs for NI didn't help.

(cherry picked from commit 4eead99)
