Fix gpg command mangled by Cloudflare email obfuscation

Cloudflare's Email Address Obfuscation rewrites literal email

 These addresses don't work in a normal browser. You need Tor Browser, which routes your traffic through the Tor network. It's a five-minute setup:
 
 1. Download it from **[torproject.org/download](https://www.torproject.org/download/)**.

Fetch the Tor Browser signing key (the fingerprint is published on the download page and in the Tor Browser manual), then check the file:
    ```bash
-   gpg --auto-key-locate nodefault,wkd --locate-keys [email protected]
+   # import the signing key — see the .asc link on the download page
    gpg --verify tor-browser-*.tar.xz.asc tor-browser-*.tar.xz
    ```
 3. Extract and run it. Windows and macOS get a normal installer; on Linux, extract and run `./start-tor-browser.desktop`.
