INFRA-27679 - Avoid squash to avoid new very large commit on each new

website build

the newly created very large commit created on each push might be the
cause of the 404 as the CDN might have problems to handle it right away.
Based on https://issues.apache.org/jira/browse/INFRA-27679?focusedCommentId=18062765&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-18062765

It means that the history will grow. So we might need to ensure that the
checkout of this site is either done with a depth of 1 or if already
available and just a pull is done maybe to squash one time manually from
time to time.
see https://issues.apache.org/jira/browse/INFRA-27679?focusedCommentId=18073130&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-18073130
