remove or edit "Using Rust without SDK"

[letmejustputthishere]

In general it is confusing that this part comes right at the toplevel of the cdk-rs page. If we keep it, it should be moved into it's own sidebar item instead

keep this section?

in the Using Rust without SDK section, the most important part – modifying the default dapp – is missing.

Can users actually "easily" write Rust canisters and deploy them without using any of the crates/the sdk? If yes, add a code example to this section. If no, I'd remove the section entirely.

I think we should remove it. Less than 1% of the users would use this section. And if you would like to use this section, it wouldn't help you. @sesi200 agreed?

I'm ok with removing it. If you're that into low-level stuff you'll probably do fine just from reading the IC spec
