Update the release script to create a tag but not a branch

+#   Create a new tag for a release of edx-ora2 and
+#   push it to the remote.
+#
+#   Release tags have a uniform naming scheme that includes
+#   the current date.
+#
+#   Usage:
+#
+#       ./release.sh COMMIT
+#
+#   If no commit is specified, use origin/master.
+#
+#   Examples:
+#
+#       Create a release tag for origin/master:
+#       ./release.sh
+#
+#       Create a release tag for a specific commit:
+#       ./release.sh f921f3ee4bc07edf2f1b492f94350cb1dd844100
+#
+#       Create a release tag without user input:
+#       yes | ./release.sh
