PR summary

Chain of PRs for #341, install the environment of a workflow with only a package manager. Merge in order: #361 → #362 → #363 → #348 → #364

Closes #341.

PowerShell port of ewoks-install.sh (#348), with the same options and steps, --install-package-manager included:

& ([scriptblock]::Create((irm https://ewoks.readthedocs.io/en/stable/ewoks-install.ps1))) demo.json

• Runs in Windows PowerShell 5.1 and PowerShell 7. The tests also run it with PowerShell 7 on Linux and macOS.
• Tests: the tests of Add the ewoks-install.sh script that installs a workflow environment without ewoks #348 also run with pwsh and powershell. The CI job tests-package-manager-install also runs on Windows.
• After installing Miniforge, the script reinstalls conda-launchers. Without it, conda cannot create environments: Disabled safety checks omit paths_data and break Windows launcher lookup conda/conda#16856.
• The tests set PIXI_CACHE_DIR: on CI runners without a user profile, pixi finds no cache directory.
• Docs: Windows tabs for the script.

Did a very shallow review of the script. The rest look good.
