New release

[Phil Holmes]

I created a new release today.  I know that (again) I got the news wrong and 
will need to fix that.  However, it looks like the web docs are probably not 
correctly picking up a style sheet (see 
http://lilypond.org/doc/v2.21/Documentation/contributor/index_1#Introduction-to-contributing 
as a simple example) - they're certainly not presented correctly.  Could 
anyone say what has gone wrong and what needs to be done to fix it?
