Allow modifiers for open website shortcut (#9186)

Minimal changes borrowed from https://github.com/FreshRSS/FreshRSS/pull/8990

Allows usage of <kbd>Ctrl/Shift</kbd> keys with the open website shortcut, so that you can open an article either in a new background tab or a new window.

Doesn't work in Chromium browsers, the website opens normally in a new tab there instead. (Firefox only)
