[bug#63483] [PATCH v2 3/4] build: Use the po4a command for the translation generation.

[gemmaro]

* configure.ac (Documentation translation): Remove the po4a-translate command.
This command has been replaced by the po4a command and are not used from
anywhere.
* doc/local.mk ($(srcdir)/%D%/guix.%.texi, $(srcdir)/%D%/guix-cookbook.%.texi)
($(srcdir)/%D%/contributing.%.texi): Use the po4a command instead of the
po4a-translate for the translation generation.  This eliminates the warning of
po4a-translate; "po4a-translate is deprecated.  The unified po4a(1) program is
more convenient and less error prone."
(PO4A_PARAMS): Remove the Texinfo format option.  This option is specified in
the configuration file (po/doc/po4a.cfg).
(dummy_pot): Add a variable for the temporary POT file location.
