I also updated the version of rust used due to a failing CI

Either upgrade rustc or select compatible dependency versions with
`cargo update <name>@<current-ver> --precise <compatible-ver>`
where `<compatible-ver>` is the latest version supporting rustc 1.82.0

This came in as part of

• Bump the MSRV to 1.85.1 due to transitive dependencies (aws-sdk) apache/datafusion#16728

I think it deserves a mention in the upgrade guide. I will do so

[ion-elgreco]

@alamb we pinned the aws sdk libraries actually so that we didn't have to bump our rustc version
