Rename "left text" and "right text" in the editor and add descriptions

Description

User made a note that "left side text" and "right side text" does not mean much to him.
This is totally correct, especially for the first time authors.
Also, it is not accessible to use "left/right" wording

Rename these fields and add descriptions so it says:

Text*
This text will display in the first column and the viewer will have to match it with the text below

Matching text*
This text will display in the second column and the viewer will have to match it with the text above
