[opengl-variant] Text not selectable in info box (so links are not too)

**Describe the bug**
Text in the the bottom info box for every package is not selectable so provided (usually pretty long) links are not selectable for copy nor are clickable.

**Expected behavior**
Select (and copy) text from the info box

**You have a solution?**
Change type of info box?

**UAD Version**
v 0.51 (OpenGL) -- pre-release

Look for the info box UI component in the OpenGL variant of the GUI code, likely in a Rust file handling widget creation or text rendering. Check if the text element has selection disabled or is set as non-interactive. Modify the widget properties to allow text selection and copying, then test by running the app and verifying links in the info box become selectable and clickable.
