ci: release on every push on main to backends channel

Description

Release backends on every push on main to backends channel

EDIT: Only happens when relevant paths are touched

How Has This Been Tested?

I ran the following locally and it looked fine. But we'll only know for sure after merging:

pixi run generate-matrix | from json

Wouldn't it be better to only release when something changed in the backends?

Ok, that seems to be the case :)

Yeah, but to be fair, arguably we should also release if something changed in Pixi, since the backends depend on Pixi.

But then we would release a lot

Doing this on every merge to main is something I turned off in the backends repo because we're dealing with heavy queues.

What is the reason we would want this again?

So people can test latest changes easily.
This version is much more lightweight, so I feel confident in giving this approach another try

[Hofer-Julian]

Remove that before merging.

Unless it's super fast, we should maybe also only release on tag

[ruben-arts]

For easy testing you could make this labeled, e.g.:

on:
  pull_request:
    types: [ labeled ]

jobs:
  build:
    if: ${{ github.event.label.name == 'release:backends' }}

Just an idea that came to mind, not Merge blocking ;)

[Hofer-Julian]

Good idea!

Why are unit tests not run on windows?

[ruben-arts]

The original setup only ran it on ubuntu-latest. I don't see a reason to extend that to more OS's
