Brainstorming: Handling Qt license information

[jarolrod]

Using Qt as an open-source application, it appears we have to have some form of an about Qt page that either provides the GPL license or links to it; but I could be wrong. Opening this to see what Qt specific information we should have before releasing any V1.

See:
https://www.qt.io/licensing/
https://www.gnu.org/licenses/gpl-howto.html
https://doc.qt.io/qt-6/qtqml-index.html#licenses-and-attributions

If we need a license/info page, we could include a Qt version setting under Developer Options, that when clicked goes to a page that includes information about Qt.

The acknowledgment text could be the same as the one used within the Qt Widgets gui, pictured below. This text and window comes from the QApplication::aboutQt function, which we don't have available to us within how we use QML, so we'd need to write up the text and implement the page ourselves

Here's a mock-up for this screen (Figma). I just added another option in About, and then copy-pasted the text from the current license screen. I did not review whether this text is appropriate and up-to-date, that is a separate task.
