Doc: List predefined procedures for `barNumberVisibility' property. (issue 9036044)

See comment below re parentheses.  Not sure if this
is a bug in the procedure or if the suggested doc
change is incorrect (or I'm doing something wrong!)

File scm/define-context-properties.scm (right):

scm/define-context-properties.scm:143: bars (which get bar numbers in
parentheses).
I didn't get broken bar numbers in parentheses with this
procedure.  The number was just repeated.  Also you need
to insert a barline at the start to obtain bar number 1.

scm/define-context-properties.scm:164: must be set address@hidden and
@address@hidden(the rest) address@hidden
Shouldn't "the rest" be "the first numbered bar"?
