Hash/Key Type Documentation Revamp

[ACStone-MTS]

What does this PR fix/introduce?

The Hash Types document grew beyond the original formatting as more key types were added. This PR restructures the document and updates it to include new 2.0 types.

Checklist

(Delete any that aren't relevant)

• Docs are successfully building - yarn install && yarn run build.
• For new internal links I used relative file paths (with .md extension) - e.g. ../../faq/faq-general.md - instead of introducing absolute file path, or relative/absolute URL.
• All external links have been verified with yarn run check:externals.
• My changes follow the Casper docs style guidelines.
• If structural changes are introduced (not just content changes), cross-broswer testing has been completed.

I'm assuming this will break some other page links and will update accordingly.

I have questions on this PR, because some of these hashes don't match the output I see in testing. Let's get a tech reviewer or connect on Monday with someone to double-check these and see what I might be misunderstanding.

The file I checked against is casper-node/types/src/key.rs. I also used the output I shared this week from installing the counter contract on a 2.0 NCTL network.

LGTM!
