distribute: bump WinGet manifest schema 1.6.0 → 1.12.0

The winget-pkgs repository has tightened its accepted schema. Per
doc/ValidationFailureGuide.md:
- 'Manifest-Version-Deprecated: Update your manifest to use a supported
   schema version. The recommended schema version is 1.12.0
   (1.10.0 is also accepted).'
- 'Manifest-Validation-Error: Address all reported errors and resubmit.'

What changed in the template heredocs:

1. ManifestVersion: 1.6.0 → 1.12.0 in all 3 files
2. Version file: dropped Publisher/PublisherUrl/PackageName/License/
   ShortDescription (those belong in defaultLocale only).
   Replaced PackageLocale: en-US with DefaultLocale: en-US — that
   field was renamed in schema 1.12.
3. Installer file: replaced InstallerMode: interactive with
   InstallModes: [interactive, silent] (the singular 'InstallerMode'
   was removed; InstallModes is now an array per-installer or root).
   Dropped PackageLocale (not part of installer schema) and
   InstallerScope: user (no longer supported at root, only per-installer).
4. Added # yaml-language-server: $schema=... comment to all 3 files
   pointing at the official 1.12.0 JSON schemas — helps editor/IDE
   auto-complete AND validates against the same schema the winget
   validators use.

Supersedes PR microsoft/winget-pkgs#391801 (closed in same batch —
manifests there used the 1.6.0 schema and got Manifest-Validation-Error).
