fix(README): fixup lock docs

I thought that @benbjohnson had changed the lock "value" to "name" but
that doesn't look to be the case. It is OK, just fix the docs.

 ### Lock
 
 The Lock module implements a fair lock that can be used when lots of clients want access to a single resource.
-A lock can be associated with a name.
-The name is unique so if a lock tries to request a name that is already queued for a lock then it will find it and watch until that name obtains the lock.
-If you lock the same name on a key from two separate curl sessions they'll both return at the same time.
