[Feature]: `json_*` functions intellisense

Hi all,

I've been using SQLite Browser for a while. It's a nice one, thank you for the great job so far.

It would be great if the Browser supported json_* functions while typing in SQL Editor. It would be even better if, along with built-in support, it accepted custom dictionaries.

I'm currently using:

DB Browser for SQLite Version 3.12.2

Built for x86_64-little_endian-lp64, running on x86_64
Qt Version 5.15.12
SQLite Version 3.45.1.

OS: Ubuntu 24.04.4 LTS x86_64
Kernel: 6.8.0-138-generic
Shell: bash 5.2.21
DE: GNOME 46.0

thanks
