Fetched link titles replace greater-than signs with closing parentheses

When opening the link dialog with a URL in the clipboard, QOwnNotes fetches the page title and fills the link name field. For GitHub PR titles such as `devenv: 2.0.6 -> 2.1 by domenkozar · Pull Request #516939 · NixOS/nixpkgs · GitHub`, the fetched title is shown as `devenv: 2.0.6 -) 2.1 ...` because the title cleanup decodes `&gt;` and then replaces `>` with `)`.\n\nOnly `]` needs to be prevented from breaking Markdown link syntax when inserting the final link, so fetched titles should preserve literal `<` and `>` characters.
