Update molecular QPE tutorial for native Windows Arm64

[sobolevnrm]

Context

The ground-state molecular QPE tutorial is being migrated to native QDK/Chemistry functionality in #625. Its introductory setup currently distinguishes:

• native Windows on x86-64; and
• WSL on x86-64 or Arm64 through the corresponding Linux wheels.

PR #593 adds explicit native Windows Arm64 compilation, testing, and wheel-pipeline support. The tutorial must not advertise that installation path until the functionality is merged and the exact QDK/Chemistry release pinned by the tutorial publishes a native Windows Arm64 wheel.

Blockers

Do not begin this update until both conditions are met:

1. Add explicit Windows ARM64 support #593 is merged into main.
2. A QDK/Chemistry release containing Add explicit Windows ARM64 support #593 publishes native Windows Arm64 wheels, and GROUND_STATE_TUTORIAL_VERSION points to that release.

Scope

• Update 00_before_you_begin.rst to list native Windows support for both x86-64 and Arm64.
• Remove the temporary statement that native Windows Arm64 wheels are not part of the release pipeline.
• Retain WSL as a supported alternative on both x86-64 and Arm64, using the Linux setup path.
• Add native Windows Arm64 to the tutorial compatibility workflow alongside native Windows x86-64.
• Validate the pinned installation command, setup checker, scripts, and notebooks using the published Arm64 wheel.
• Keep architecture and Python-version qualifications aligned with the release wheel matrix, including any Windows Arm64 minimum Python version.

Acceptance criteria

• The tutorial's platform text matches the published wheel matrix for its pinned release.
• Native Windows x86-64, native Windows Arm64, and WSL are described without ambiguity.
• The tutorial compatibility workflow executes successfully on native Windows Arm64 using the pinned published wheel.
• tutorial_qpe_setup.py succeeds in that environment.
• Required tutorial scripts and notebooks pass their existing compatibility checks.
