`testing` unsupported

Describe the bug

Raspberry Pi does not have a testing distribution setup, so if you choose testing, it will fail trying to find the repository

E: The repository 'http://archive.raspberrypi.org/debian testing Release' does not have a Release file.

To Reproduce

# .github/workflow/build-image.yaml
name: build solar pi image

jobs:
  build:

Expected behavior Testing should work - I think this would require grabbing testing from the Debian repositories, but I am not sure if we can mix-and-match.

Opened #42 for now

Thanks for reporting this.

I actually copied the variable descriptions from the pi-gen README and just noticed that they've updated the RELEASE parameter:

The release version to build images against. Valid values are any supported Debian release. However, since different releases will have different sets of packages available, you'll need to either modify your stages accordingly, or checkout the appropriate branch. For example, if you'd like to build a buster image, you should do so from the buster branch.

Since I do not see a testing branch in their repo, I assume this is not supported out of the box and you'd have to follow their advice by editing the sources lists manually.

It makes sense to adapt the action's behavior like you suggested in the linked PR, I'm just thinking about a more general solution that better reflects pi-gen's intention (for instance dropping verification on this variable entirely and leaving it up to the user).
