Moves Hosts, Users, and Network pages to Entity Analytics section

[benironside]

Fixes #4355.

• Renames the "Advanced entity analytics" section within the security solution docs to "Entity analytics", which better matches the product IA.
• Deletes the "Explore" section within security solution docs and moves its contents to the Entity analytics section. Deletes the landing page for this section, which was a stub.
• Makes a minor update to the entity analytics landing page to reference the new pages in its section.
• Updates links and adds redirects.

Thanks for taking this, just a few small updates needed and then should be good to go 🙏
Also, we might need to update the link for the networkMap entry in the doc link service file, since the Network page in Kibana links to the Configure network map data docs.

[natasha-moore-elastic]

The solutions/security/get-started/elastic-security-ui.md page only needs the link updates.
We shouldn't remove the ### Explore [_explore] section because in the UI, the Users, Hosts, and Network pages are still inside the Explore section.

We can keep this, it stands for User and Entity Behavior Analytics and refers to the features in Advanced behavioral detections.

Can we move the Hosts, Network, and Users pages to go at the end of the Entity analytics section (after Privileged user monitoring), to match the order they're listed in on the landing page?
