Update DAL file server tutorial for Ghostnet

Update the DAL file server tutorial:

Use Ghostnet instead of Weeklynet for convenience
Run a layer 1 node as part of the environment to get around an ACL issue on some public RPC nodes
Little clarifications and corrections
Reduce reliance on setting environment variables because we're constantly opening new windows where they might not be set
Switch to --observer-profiles to be in observer mode for the DAL node
More info about what you see happening on Explorus
Add info about what happens if there are no active attesters
Add --legacy more for the DAL trusted setup
Fix Rust version to 1.80 because the kernel doesn't compile at version 1.81.

As noted in the comments, this tutorial doesn't currently work on Ghostnet because of an issue with DAL attesters. However, we may want to merge this update now anyway because it no longer works consistently on Weeklynet.

There is a note that says:

For the first 4 Tezos blocks produced after the origination of the Smart Rollup, the kernel will report that no slot has been attested for the targeted level, even if Explorus states the opposite. This is because, as of January, 2024, a Smart Rollup cannot fetch the content of a slot published before it is originated. This is why you must wait for 4 blocks before seeing slot page contents being logged.

Should this be 8 blocks for Ghostnet because that's the attestation_delay?
