ci(windows): expand runner disk cleanup to prevent TeX Live OOS

The Windows container build has failed intermittently (2026-04-05, 03-29,
03-08) during TeX Live installation with:

    re-exec error: exit status 1: output: write ...
    \texlive\tlpkg\tlgs\Resource\Font\putri8a.pfb:
    There is not enough space on the disk.

The pre-build cleanup step was only removing six toolchains. Expand the
allowlist to cover more pre-installed SDKs and package-manager caches
that the Quarto Windows container build does not use.

Added removals:
  - Android SDK, ANDROID_HOME, ANDROID_SDK_ROOT
  - Go, Java, JDK variants, dotnet SDKs
  - Unity Hub, Windows Kits ExtensionSDKs
  - PHP, Ruby, Julia, Miniconda, Rust toolchains
  - Cargo/rustup user caches, vcpkg, Selenium drivers
  - NuGet / npm / pip / Chocolatey HTTP caches
  - Windows Update download cache

Added post-prune operations:
  - Clear-RecycleBin
  - docker builder prune -af
  - docker volume prune -f

Explicitly does NOT touch: C:\ProgramData\chocolatey (scoop fallback),
C:\Users\runneradmin\scoop (build state), Docker binaries, or any
installation step in the Dockerfile.
