[Advanced Paste] - Keyboard shortcut for “copying the path”

### Description of the new feature / enhancement

In the Advanced Paste feature, add an option to include a keyboard shortcut that copies the absolute path of the selected folder or file.

This way, you won't need to hold down the “SHIFT” key, right-click on the file, and select the “Copy as path” option.

### Scenario when this would be used?

In various situations where you need to obtain the absolute path of a file, such as when installing and developing applications.

### Supporting information

_No response_

No file, test, or entry point is named in the issue. Start by locating the Advanced Paste implementation and its existing keyboard shortcut handling, then determine how shortcut settings are defined. Done means users can configure and use a shortcut to copy the absolute path of a selected file or folder without holding SHIFT or using the context menu.
