Description

Made significant updates to the doc structure.

• Deleted Local Dev Cluster section
• Deleted sections for Azure, GCP, and AWS (to be re-added once they're updated)
• Moved rollup deployment to top level on sidebar
• Updated copy in Digital Ocean guide

Motivation and Context

Screenshots (if appropriate):

Types of changes

• Edits to existing documentation
• Changing documentation structure (relocating existing files, ensure redirects exist)
• Stylistic changes (provide screenshots above)

We should consider using redirects for things that changed location/what we want people to nav to instead: https://docusaurus.io/docs/api/plugins/@docusaurus/plugin-client-redirects

Noted, this is a pretty significant restructuring of the docs so I'm not sure this applies. Is this for SEO reasons?

[joroshiba]

Yes + people having dead links is bad.

Of chance someone has a bookmark, if someone gets a stale search crawl, etc.

nit:
in local-rollup/introduction in the Create a New Sequencer Account section the private key text in the output and env var input aren't the same:
example:

Private Key: "5562...1622" # <SEQUENCER_ACCOUNT_PRIV_KEY>
Public Key:  "ec20...f613" # 
Address:     "8a2f...5f68" # <SEQUENCER_ACCOUNT_ADDRESS>

Export your sequencer private key and address as environment variables:

export SEQUENCER_PRIV_KEY=9c78...710d
export SEQUENCER_ACCOUNT_ADDRESS=8a2f...5f68

The line export SEQUENCER_PRIV_KEY=9c78...710d should be export SEQUENCER_PRIV_KEY=5562...1622

docs/docs/local-rollup/1-introduction.md

Line 210 in e438128

export SEQUENCER_PRIV_KEY=9c78...710d

This is also the case in the Digital Ocean docs in the same section.

docs/docs/cloud-rollup/1-digital-ocean.md

Line 236 in e438128

export SEQUENCER_PRIV_KEY=9c78...710d
