Add highlighted_languages

As of December 1, 2025, syntax highlighting does not appear to work when writing code using expressions like the ones below.

```bash
#!/bin/bash

if [ ! "$*" == "" ] ; then
    for i in "$@" ; do
        renoise $i &
        sleep 1
    done
else renoise &
fi

rtprio=$(expr $(ps -eLo rtprio,command  | grep /usr/bin/pipewire$ | grep -v "^ *-" | sort -r | awk '{ print $1 }') - 5)

while ps -C renoise > /dev/null ; do
    ps -eLo tid,comm | grep "Audio Slave" | awk '{print $1}' | xargs -n1 -r chrt --fifo --pid $rtprio
    sleep 5
done
```

Syntax highlighting for bash and other languages (all languages, if performance, etc is not an issue) would be useful.

Added bash and powershell highlighting now as well.

# This is a bash script 
echo "Wurst"
# This is a powershell script 
Write-Output "Kรคse"
