fix: substrate/dev dep, update changelog

[TarikGul]

Update @substrate/dev dep,

Update the changelog from an emergency release last week.

[niklasad1]

just fix the date in the CHANGELOG and it's good to go

[jsdw]

out of interest, what's the difference between substrate-exec-* and *?

[TarikGul]

@jsdw so we run all binaries via scripts from @substrate/dev which allows us to have all of our deps and configs in a centralized package, and under our control is all. It's more for consistency
