Support f-strings

[chdsbd]

We should update the syntax to support f-strings.

this is what vs code reports as scope https://code.visualstudio.com/api/language-extensions/syntax-highlight-guide#injection-grammars

textmate scopes 
string.quoted.multi.python
string.interpolated.python
punctuation.definition.string.begin.python
meta.fstring.python
meta.function-call.arguments.python
meta.function-call.python
meta.member.access.python
source.python

Incidentally, I am only using f-strings because I could not find how to do prepared statements in DuckDB https://github.com/duckdb/duckdb/discussions/11262
