GS review sprint: Ch11 done

I have reviewed and copy-edited Chapter 11, Graphics Gallery Fontwork.
I made some minor corrections (e.g., missing words), plus a response
to one of DB's comments.

I wasn't sure where to put it after review, so it's here:
https://www.odfauthors.org/libreoffice/english/getting-started/feedback-lo-6.0/gs6011-graphics-gallery-fontwork-1/view

I see in the minutes of yesterday's meeting that Chapters 7 (Draw) &
13 (Macros) have been done, but the wiki page doesn't show that.

I have taken Chapters 3 (Styles & Templates) and 5 (Calc) for a final check.
