Update ETH Staking Keys docs to reflect `lattice-eth2-utils`

[alex-miller-0]

In #508 we removed bespoke test functionality related to BLS in favor of using lattice-eth2-utils.

I forgot to update the docs, which are now out of date: https://gridplus.github.io/gridplus-sdk/tutorials/ethDeposits

We should update the docs and maybe ship a fix version so that people don't get confused looking at that.

Perhaps we should actually move this to a new section... it doesn't really belong with the other sections, which describe how to do things with the SDK. Here we should explain how to do things with another tool, which happens to itself use the SDK...

We could move all the docs to docs.gridplus.io. It's not ideal, but we can ship markdown to that service, so I bet we could migrate over in a few hours. The biggest issue with that would be ongoing maintenance.

Perhaps we move all the manual docs to the docs.gridplus.io, then keep the automated docs as a reference? Or just remove the automation entirely?

What do you mean by manual vs automated docs?

[douglance]

Everything under the API heading is auto-generated.

Gotcha.

Yeah so a few points here:

• There are basic SDK tutorial docs like the signing pages. I think these make sense to stay in the SDK docs page with the autogenerated docs
• I created a separate bucket called "Tutorials" for patterns that might be used by integrations. These tutorials include calldata decoding and address tags. These should probably also stay in the SDK docs, imo.
• In the Tutorials section we also have ETH Staking Keys, which was meant to be a "higher order" doc on how to do ETH2 stuff. However, all of this has gotten moved to lattice-eth2-utils. I'm not sure where to put these docs. One option is to create a new section for "using external utils" or something and put the ETH2 stuff in there. Another option is to add a very short description of lattice-eth2-utils and link out from the SDK docs, then to add an explanation of the CLI actions in the official GP docs. In the CLI docs we will also link out to lattice-eth2-utils for developers.
• Basically we need two things: 1) How do we show developers where to go to integrate the Lattice for ETH2 functionality (note that there probably isn't going to be a lot of ETH2 integrations anytime soon). 2) How do we show users what ETH2 functionality their Lattice can do? This would need to include the CLI because that's going to be the easiest user facing interface for now. We can look into adding a manager page but it will be a bit complicated and anyone generating keystores is probably at the command line anyway.

Actually, it might make sense to just put all the staking stuff into docs.gridplus.io because it's really end-user content. It's not technically for developers. It's for users of the Lattice.

I agree. I guess we can just link to lattice-eth2-utils in a note for developers
