Cannot resolve non-ascii url-encoded JSON schema url

When I apply JSON schema with URL including non-ascii character, Unable to load schema from '...': Request path contains unescaped characters. warning occurs despite the URL being URL-encoded.

Steps to Reproduce

1. Open a new VSCode window.
2. Open a new file.
3. Write JSON code as below:

{
  "$schema": "https://libertygame.miraheze.org/w/index.php?title=%EB%A6%AC%EB%B2%84%ED%8B%B0%EA%B2%8C%EC%9E%84:%EA%B2%8C%EC%9E%84_%EB%A9%94%ED%83%80%EB%8D%B0%EC%9D%B4%ED%84%B0/%EC%8A%A4%ED%82%A4%EB%A7%88.json&action=raw&ctype=application/json"
}

What happened

Unable to load schema from 'https://libertygame.miraheze.org/w/index.php?title=리버티게임:게임_메타데이터/스키마.json&action=raw&ctype=application/json': Request path contains unescaped characters. warning occurs. The URL in the warning message is URL-decoded. I think it decodes the URL and tries to resolve the schema with decoded URL so that error occurs.

Warning message data

[{
	"resource": "Untitled-1",
	"owner": "_generated_diagnostic_collection_name_#1",
	"code": "768",
	"severity": 4,
	"message": "Unable to load schema from 'https://libertygame.miraheze.org/w/index.php?title=리버티게임:게임_메타데이터/스키마.json&action=raw&ctype=application/json': Request path contains unescaped characters.",
	"startLineNumber": 2,
	"startColumn": 16,
	"endLineNumber": 2,
	"endColumn": 246
}]

What should it be

JSON schema should be imported successfully without any errors. I believe the schema in that URL is valid.

Environment

• VS Code Version: 1.76.0
• OS Version: Windows 11 Version 22H2 Build 22621.1344 (Windows_NT x64 10.0.22621)

Start by reproducing schema loading with the non-ASCII, URL-encoded URL from the issue and trace the JSON schema URL resolution request path. Done means the schema imports successfully without a “Request path contains unescaped characters” warning.
