Description

I'm parsing the following file (quoted strings, non-quotes numbers):

name,age,city
"Chirstian",30,"Hamburg"

The option dynamicTyping detects name and city as strings and the age as number. If I unparse, I have two options.

Option 1) set quoteChar: '"', which results in:
name,age,city
"Chirstian","30","Hamburg"
Option 1) Skip the option `quoteChar, which results in:
name,age,city
Chirstian,30,Hamburg

I recommend an option onlyQuoteStrings, which applies the quoteChar: '"' only to strings, but not to numbers, similar to libre office save as CSV dialogue (option quote all text cells):

Research direction
Examine the unparse function in the PapaParse source code (likely papaparse.js or src/unparse.js) to understand how quoteChar is currently applied. Consider adding a new option onlyQuoteStrings that, when true, applies quotes only to string values while leaving numbers unquoted. Review existing tests for unparse to ensure new behavior is tested.
