Added missing dependency and updated cargo version

[bindsi]

• updated cargo version in the toolchain install instruction to version 1.70 as it is required by cargo-generate which is used to create a discovery-handler project from a template
• added "html" package import to the Go module for the http server because it is required as dependency in the build step (docker build)

@diconico07 thanks for your approval. Who is gonna merge this?

[diconico07]

@Bindsi , I will in a few days, or some other maintainers if they take a look before that. We tend to let a bit of time for other reviewers to have another look before merging after an approval.

the akri repo setup.sh still use 1.68.1, do we need to update rust version in code repo, too?

@johnsonshih: yeah, you are right...but I see that it is not compiling with 1.70 because dependencies require 1.68.1 and are tightly coupled to that version by the cargo.lock checked in in codebase...mmh, wondering if I should create an issue for that and trying to resolve it...wdyt?

please create an issue to keep track of the problem, thanks! BTW, for the Cargo.lock issue, remove the Cargo.lock file or run 'cargo update' should help.
