git-sh-i18n--envsubst: add SYNOPSIS section to the documentation

Change the documentation for the git-sh-i18n--envsubst program to include a SYNOPSIS section. Include the invocation of the program from git-sh-i18n.sh. Not having a SYNOPSIS section caused the "doc" target to fail on Centos 5.5 with asciidoc 8.2.5, while building with 8.6.4 on Debian works just fine. The relevant error was: ERROR: git-sh-i18n--envsubst.txt: line 9: second section must be named SYNOPSIS Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
