ref: deprecate digest option from HTTP remote

[isidentical]

We have removed the digest option in iterative/dvc#6525

[efiop]

Let's not remove it, but just clarify that it has been removed and put a link to a ticket in dvc repo, so people could give us feedback.

[jorgeorpinel]

Agree to leave it for now with a note on which version it was removed but do we need to link to some GH ticket? I'd prefer to avoid that. Users can reach us via regular channels with feedback. Or is there a special reason we want to encourage feedback on this? Thanks

[efiop]

@jorgeorpinel Just to have 1 place to point people to.

[shcheklein]

Was it deprecated or removed though?

[efiop]

The difference is vague. I've suggested to include a link above, but that might be excessive. The current approach will work fine for now.

[shcheklein]

Agreed on the link. It's more of a question - keep deprecated term or use remove. Even from the conversation you both have here:

but just clarify that it has been _removed_
which version it was removed
We have removed the digest option

it seems that it was removed? So, why don't explicitly say removed in ...

Passing back to core team.

[jorgeorpinel]

I changed to "removed".

I don't like the idea of linking to GH issues in general (seems fragile; we already have a few which are probably no longer relevant) but feel free to add the link to the appropriate ticket (I'm not sure which one @efiop referred to) and merge @isidentical.
