Add default shortcut Ctrl+I for making letters Italic

**Describe the bug**

I am using CopyQ on MX Linux (Debian 12).
I would like to request adding "Ctrl+I" as a default shortcut for making letters Italic.

**To Reproduce**

After selecting some text in the editor, pressing "Ctrl+I", but nothing happens.

**Expected behavior**

I expected "Ctrl+I" to toggle italic formatting for the selected text in the editor, just like in other text editors.
