pin smithy-rs-tool-common with lockfile

[aajtodd]

Description

Seeing preview build failures across the board. Looks like [email protected] was released a few hours ago and comes with a new MSRV of 1.81. We don't have a lockfile for smithy-rs-tool-common for some reason. This PR adds one.

~/sandbox/rs/smithy-rs/tools/ci-build/smithy-rs-tool-common on main ✗                                                                            [41d648dd6]  12:14
> cargo check
error: rustc 1.78.0 is not supported by the following package:
  [email protected] requires rustc 1.81
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 1.78.0

Added a lockfile and downgraded home:

> cargo update [email protected] --precise 0.5.9

Testing

Build locally + CI.

Questions

Lockfiles do not appear to be updated automatically for anything under ci-build unless I'm missing something. This is probably fine as our use of lockfiles is intended to catch issues with consumers of smithy-rs and the SDK not our own internal tooling.
