Osquery Docs cleanup

[bmorelli25]

Description

Kib reference

The existing kibana reference page is redundant with the official osquery docs.

1. Remove the page.
2. Add a redirect to the Osquery integration page.

Integration doc

The existing integration docs page needs to link to extra resources and change a heading name.

1. Link from the Osquery integration docs to official field docs: https://osquery.io/schema/5.20.0/4
2. Rename the “Documentation” section in the integration to “Investigate with Osquery”
3. Link to the Osquery github tables

   There are Elastic osquery tables that exist but are not documented (i.e., host_groups) and we are planning to add more tables in 9.3 like Amcacheand Browser history. In future releases, we will add more tables.
