Blocked on microsoft/winget-pkgs#335606.

Fixes #1888

Add Winget install lines for both tools and note Winget packages in the release outcomes.

Note

Medium Risk
Introduces a new release-pipeline publishing step that depends on correct artifact naming/regex and a new secret token; failures or misconfiguration could break automated releases but doesn’t affect runtime behavior.

Overview
Adds a new publish-to-winget job to the release GitHub Actions workflow to automatically submit/update two WinGet packages (for vws-cli and vuforia-cloud-reco) using the Windows .exe artifacts and a WINGET_TOKEN secret.

Updates docs (README.rst, docs/source/install.rst, docs/source/release-process.rst) and the CHANGELOG.rst to advertise WinGet install commands and include Winget packages as a release outcome, plus adds winget/Winget to the spelling dictionary.

Updated the Winget release workflow to use specific installer regexes and added a separate step for vuforia-cloud-reco. This prevents vuforia-cloud-reco being attached to the vws-cli package.

Added 'winget' to the spelling dictionary to fix the spelling job failure from run 21562234483.

Added to the first winget-releaser step so both releases use the PAT. Also fixed the duplicate token entry introduced by the last change.
