Workspace symbol picker should hihglight the matched chars like other pickers do

[TadoTheMiner]

In most pickers, the matched chars are highlighted. For some reason though, this isn't the case for workspace symbol picker. This seems like an easy issue so i could do it

This is actually a problem with dynamic query in general

[the-mikedavis]

The highlighting is intentionally skipped for dynamic columns since they can't be reliably highlighted the same way as normal columns. Normal columns always use fuzzy matching but dynamic columns can use whatever filtering they want. The global search picker searches with a regex and the workspace symbol picker's filtering is up to the language server, so we can't reliably tell which characters in the filter matched what parts of the results.

Maybe we can do some "best effort" matching of the characters in the filter to the results though
