feat(runner): Container detection and handling, video bit-depth flags and script updates (#303)

## Description

Works in apptainer now.. podman is still the goat since apptainer needs
docker treatment and even more..

- Added container detection so podman can be used to it's fullest, the
non-sane ones are handled separately..
- Added video bit-depth option, cuz AV1 and 10-bit encoding go well
together.
- Some other package updates to nestri-server.
- General tidying up of scripts to make multi-container-engine handling
less of a pain.
- Updated old wireplumber lua script to new json format.

Further changes:

- Removed unused debug arg from nestri-server.
- Moved configs to config file folder rather than keeping them in
containerfile.
- Improved audio configs, moved some into wireplumber to keep things
tidy.
- Bit better arg handling in nestri-server.
