Adds a registry entry that allows any WebView2 enabled app to discover the runtime installed by Scoop.

Reference: https://ntlite.com/community/threads/webview2-portable.5560/

The WEBVIEW2_BROWSER_EXECUTABLE_FOLDER variable isn't sufficient for apps to discover the runtime.
Since the WebView2 Loader will actually load into the registry if the app isn't specifically configured to read the variable.

📝 Walkthrough

Walkthrough

This PR updates the WebView2 JSON manifest with installer and uninstaller scripts. The installer computes the runtime path and registers the EBWebView value under the current user’s WebView2 registry key. The uninstaller removes the registry value with suppressed command output. The JSON structure includes the final closing brace.

Estimated code review effort: 2 (Simple) | ~8 minutes

Merge Risk: ⚪ Minimal · up to 0c9e5

The change adds and removes a per-user registry value intended to help WebView2-enabled applications locate the bundled runtime; no concrete correctness or security defect is currently established, so no actionable merge-blocking risk remains beyond normal validation.

- Around line 36-38: The uninstaller script currently deletes the entire
ClientState registry key; update the "uninstaller" -> "script" so it deletes
only the manifest-owned value instead of the key by using reg.exe with the /v
"EBWebView" option (targeting the same
HKCU\SOFTWARE\Microsoft\EdgeUpdate\ClientState\{F3017226-FE2A-4295-8BDF-00C3A9A7E4C5}
path) and keep the /f and Out-Null behavior; locate the "uninstaller" object and
replace the reg.exe delete command accordingly.
