[DOCS] Update incorrect references to "Index pattern" to "Data view" for 8.0.0

[benironside]

Addresses #1373

Previews:

• Anomaly detection with machine learning
• Investigate events in Timeline
• Tune detection rules
• Configure network map data (This one is a bit weird in that there were two .asciidoc files that contained the copy that needed updating, where I made identical changes, but I couldn't find two corresponding web pages for them. There's only one preview, but two diffs that correspond to it — the bottom two as listed under Files changed above. Any insight on this would be very welcome.)

@benironside re: your last bullet point above: I think the duplicate text for network map data that you found is related to the older SIEM Guide. The source files for SIEM Guide live in the security-docs repo and contain some of the same content as the newer Security Solution docs. @jmikell821 might know more about the SIEM Guide?

Looks good! A few small fixes.

LGTM overall! Just some minor questions and recs. Thanks for this!

Correct. Prior to 7.9 all the docs were in the SIEM Guide, so you may see some duplicates, but those are totally fine to ignore because we aren't really updating anything from <=7.8.

Hey @benironside just a few small things:

In the ML topic, let's wrap this in bold text.

The "Add data" link at the top of the main pages has been replaced with "Add Integrations".

Should be a simple stitch image editing rather than taking new screen grabs altogether. Not a huge deal but would like the Timeline pages in this PR updated before QA files a bug.

LGTM on the index pattern/data view terminology. Thank you!
