etc: snippets: Fix name extraction.

* etc/snippets/text-mode/guix-commit-message-update-package: Since git commit
mode is not derived from any Lisp mode, so-called sexp or symbols do not
include the period character.  As a consequence, names including versions are
not properly extracted. Also use more idiomatic (goto-char (point-min))
instead of (beginning-of-buffer).
