chore(trusted.ci.jenkins.io): ouput to generate a zip of update cente…

…r env files to access file shares (#690)

This PR adds an output with a command to generate a zip containing two
env files:
- .env-content for updates-jenkins-io File Share
- .env-redirections for updates-jenkins-io-httpd File Share

This zip file has to be uploaded as zip credentials on
trusted.ci.jenkins.io for the update-center2/site/publish.sh script to
work.
