getLinuxOSNameVersion fails in debian:unstable/testing docker

[liskin]

I'm trying to use setup-uv in a GHA workflow with container: debian:unstable, but it fails with:

Error: Failed to determine Linux distribution. Could not read /etc/os-release or /usr/lib/os-release

I believe this is because if enable-cache: "true" (the default), this line raises:

setup-uv/src/utils/platforms.ts

Line 108 in 0098a75

const versionId = parseOsReleaseValue(content, "VERSION_ID");

There's no VERSION_ID in the unstable/testing version of base-files.

Full workflow:

name: XXX

on:
  push:

jobs:
  xxx:
    runs-on: ubuntu-latest
    container: debian:unstable
    steps:
      - name: Install prerequisites via apt
        env:
          DEBIAN_FRONTEND: noninteractive
        run: |
          set -ex
          apt update
          apt install -y git
      - uses: actions/checkout@v6
      - name: Install uv
        uses: astral-sh/setup-uv@v7

(Works fine with enable-cache: "fa;se", so that's a workaround for now.)
