 Trying to address some issues noticed when discussing #36450.

 The "browser interface" image used for the sidebar control has an alt
 attribute 'Browser interface preview' that should be removed for
 consistency with the same image used in the Media dialog.

 Also, some text is redundant when using a screen reader:
 - the bold text and the alt attributes say the same thing
 - the site name is just for visual purposes, should be hidden for
 assistive technologies

 About the image crop preview, the whole cropping task is not accessible at
 the moment so the best thing to do is probably just use an alt attribute
 to say what the image is and that cropping requires mouse interaction.

 Props from #36450 go to shahpranaf and TacoVerdo.

 In the screenshots below, the highlighted text should be hidden for
 assisitive technologies because it just repeats the images alt attributes
 or because it is not useful (e.g. the site name).
