I found a tiny mistake in the swap chain chapter.

There is actually one more small things that need to be decided upon, but it's
so simple that it's not really worth creating separate functions for them. The
first one is the number of images

in 03_Drawing_a_triangle/01_Presentation/01_Swap_chain.md

The first sentence needs to be either "two" instead of "one", or the plural is wrong.
What's slightly confusing is that the second sentence talks about the "first one", but I can't find a second one.

Best, Ronny

P.S.: If you clarify this, I can create a PR, too.
