ci/windows: Make Chocolatey installs more reliable

Chocolatey installs depend on downloading binaries from SourceForge,
which is an unreliable host: container builds often fail because it
cannot pick up winflexbison.

Add a loop to retry chocolatey installs if any installs have failed, and
ensure Python is in the accessible PowerShell path rather than relying
on the path being externally refreshed.
