Ctrl+F search does not work for shortcuts on "Default editor shortcuts" page

**Your Godot version:** 4.6.2

**Issue description:**

I am unable to use the browser's native search function (Ctrl + F) to locate shortcuts on the "Default editor shortcuts" page.

For example, the shortcut for "Open 2D Workspace" is listed as `Ctrl + F1` on the page, but searching for that exact string yields no results.

Searching for `Ctrl` correctly highlights the appearances. But `Ctrl+` and `Ctrl +` highlights nothing.

There might be something wrong with the html markup of these shortcut keys.
