Motivation, issues

see #67

the tag-pattern conditions are missing brackets that are causing them to error

Description

the conditions were

[ -n "${CIRCLE_TAG:x}" && "<<parameters.tag-pattern>>" != "" ]

resulting in error while running

environment: line 23: [: missing `]'

added brackets, now they are

[ -n "${CIRCLE_TAG:x}" ] && [ "<<parameters.tag-pattern>>" != "" ]
