[DOCS] Add redirect for GSuite module (#30034)

Adds a redirect for the [GSuite module](https://www.elastic.co/guide/en/beats/filebeat/7.17/filebeat-module-gsuite.html) page, which has been removed in 8.0+.

We saw this missing page create several broken links in elastic/docs#2312. I've opened elastic/security-docs#1441 to update those links. This adds a redirect for anyone who otherwise lands on the page.

(cherry picked from commit 11e488d)
