(bug 43032) file containing typos for Jenkins

The operations-puppet-typos Jenkins job only catches one typo 'pmpta'
which is done by using grep on all the files.  Faidon proposed to read
the grep pattern from a file.  The 'typos' file has been added to
operations/puppet.git with https://gerrit.wikimedia.org/r/47409
