Fix issue_closing_regex in gitlab.yml.example
Created by: smashwilson

Before (with issue_closing_pattern uncommented):
smash@winter:config example-config-fix *$ irb -ryaml
2.0.0-p247 :001 > YAML.load_file('gitlab.yml.example')
Psych::SyntaxError: (gitlab.yml.example): found unknown escape character while parsing a quoted scalar at line 52 column 28After:
smash@winter:config example-config-fix *$ irb -ryaml
2.0.0-p247 :001 > YAML.load_file('gitlab.yml.example')
