help-bash pointer added to web page

[Bob Proulx]

One of the recent postings mentioned that http://www.gnu.org/software/bash/
directed questions to bug-bash.  We never updated the web page to
mention the new help-bash mailing list!  I updated the web page to say
to send questions for help with bash to the help-bash list and bugs or
development issues to bug-bash.
