Highlight digit groups in Pretty formats

Why it matters

This feature improves the readability of Nullable numeric values when using Pretty output formats by applying digit grouping highlights. It solves the problem of inconsistent or missing digit group visualization for numbers that can also be NULL, making it easier for users to interpret query results with Nullable numeric columns.

How to use it

Simply output your query results using any Pretty format (such as Pretty, PrettyCompact, or PrettySpace) on tables or expressions that return Nullable numbers. The digit grouping highlighting will be applied automatically without any additional configuration.
