Description

Apache Zeppelin currently has a separate gh-pages branch for project pages.and Travis-Ci content remains on the 'Contribution Guidelines' page of the gp-pages branch.(https://zeppelin.apache.org/contribution/contributions.html)

Currently, Zeppelin uses two ci types: github action and appveyor, so it would be better to delete this content.
