Scripting: add addRadioButtonGroup to Dialog

[dogboydog]

Fix #3478

TODO @dogboydog

• Update scripting API doc
• Update News.md
• Fix radio buttons being invisible
• Provide example of responding to selected option changes
• Provide a way to select one of the radio buttons from the script?
• Decide on tooltip API

Currently I'm trying a few different things to try to get the radio buttons to show up. They seem to be invisible. Tried putting them in a QHBoxLayout and that didn't seem to help . Trying to do something like the example here
https://doc.qt.io/qt-6.5/qgroupbox.html#flat-prop

Also planning on looking at #4014 in the future, and thinking I should start providing the tooltip optional argument on this widget. Only thing is in this case (and with the combo box) the tooltip would be for the whole button group, which might be less useful than per radio button. I guess you could embed a description of all the options in your tooltip though.

Edit: Just added. Example:

Would it be possible to have the tooltip method accept an array of tooltips, one for each radio button?
