fix(git-id-switcher): add User-Agent to Webview fetch (#306)

Node.js fetch in the extension host doesn't include VSCode's User-Agent
(Code/x.y.z), causing Cloudflare analytics worker to classify documentation
access as OTHER/is_likely_human=0. Now sends Code/${vscode.version} to match
existing classifyTraffic detection rules.

Now sends `Code/${vscode.version} git-id-switcher` to match existing `classifyTraffic` detection rules.
