Settings.json incorrectly marks permitted extension versions as not accepted

[intelligent-box]

Description

In 1.129.1, it was possible to allow specific versions or platforms when specifying a list of approved extensions, as documented here: https://code.visualstudio.com/docs/enterprise/extensions#_allow-specific-versions-or-platforms
In 1.130.0 this feature no longer displays properly, instead showing the warning:
"Incorrect type. Expected one of boolean, string.
Value is not accepted. Valid values: true, false, "stable".(1)"

This is the warning given when the following settings snippet is placed in my settings.json file; where the "1.31.3" is marked with a yellow underline.

"extensions.allowed": {
    "GitHub.copilot-chat" : "stable",
    "ms-vscode.cpptools" : ["1.31.4"],
...
}

In spite of this warning, the extensions with versions specified still work as normal, so I suspect this is a format/display issue more than the core functionality not supporting this anymore.

@aeschli Could you please confirm this analysis? PR #325505 upgraded vscode-json-languageservice from 6.0.0-next.1 to next.2, which includes the upstream fix to validate a property against every matching patternProperties schema. That exposed overlapping unanchored patterns in the extensions.allowed schema: an extension ID such as ms-vscode.cpptools matches both the extension-ID and publisher patterns, and the publisher pattern rejects version arrays. Runtime handling still accepts the arrays. Anchoring the patterns removes the diagnostics.
