Remove +nightly qualifier because of rust-toolchain

[pepyakin]

This repository already has rust-toolchain file, but at the present in all build.sh there are inconsisency:

the first cargo invocation is without a qualifier
then the second cargo invocation is with +nightly qualifier

this means that build.sh will typically download the required toolchain, but then will use nightly. This might be a problem if nightly version is outdated.

We should not forget to also change this in the rudimentary CLI tool.
Could you also pls rename the commit as noted in the contribution guidelines? :)

What do you mean? If cli/src/cmd/new.rs then it is already in : )

Sure, [chores]?

Ah you are right I didn't see it!
[chores] sounds good for that but I have the feeling that in reality we are missing some further categories that we might want to add. Thanks!
