[alreq] Expand on the “ligatures” section

mostafah has just created a new issue for 
https://github.com/w3c/alreq:

== Expand on the “ligatures” section ==
Our [ligatures section](http://w3c.github.io/alreq/#h_ligatures) 
(currently numbered as 2.4.2) only talks about lam and alef ligatures.
 It should cover other ligatures as well.

Also, this is the last sentence of the section:

> Each of these ligatures also provides a special shape for joining 
from its right side (to the preceding letter).

It is talking about variations of the lam and alef ligature, but 
that’s not clear enough and it can confuse readers into thinking that 
all ligatures are right-joining only.
