[Rule Tuning] Fix links to the Filebeat Google Workspace module

[jmikell821]

The links to the Filebeat Google Workspace module need to be updated so they don't break when we change the current Stack version to 8.0.

Changes were made in elastic/security-docs#1441, so they need to be duplicated in the rules repo so that when they are regenerated, it doesn't overwrite the edits that were made in the Elastic Security docs.

Relates to elastic/docs#2312.

@jmikell821 I've updated all the gsuite references to google_workspace in https://github.com/elastic/detection-rules/pull/1706/files
There is any other changes that need to be done?
