use same rust version in every action

[marcoieni]

The Deploy job in #2425 failed with the following error:

error: rustc 1.94.1 is not supported by the following package:
  constant_time_eq@0.4.3 requires rustc 1.95.0
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 1.94.1

This PR fixes these issues because we use the same rust version in all workflows.
