small typo in guile 2.0.x and 2.1.x documentation for r6rs conditions

[Freja Nordsiek]

I found a small typo in the documentation for the r6rs conditions
library in both the 2.0 and 2.1 series. Ordinarily, this would be
small enough to not be worth going to the trouble to fix, but since it
is in the library name, it could cause someone trying to import the
library a lot of trouble to figure out what is wrong and why the
library can't be found (just fought with it myself for quite a while).

The typo is in the first sentence in the library name. It says

"(rnrs condition (6))"


which is missing the 's' in "conditions". An 's' needs to be added to make it

"(rnrs conditions (6))"
