Documentation consistency in the Arrays section

[Jeff Schaller]

The bulk of the array declaration examples do not have a period at the end,
making http://git.savannah.gnu.org/cgit/bash.git/tree/doc/bashref.texi#n7190
a needlessly confusing example. I'd like to propose removing the period at
the end:
