[MSRV] | Dependency updating when bump new MSRV

[Xynnn007]

Due to confidential-containers/confidential-containers#258 (comment)

We are currently facing a lot of Dependabot update PRs, but the new version requires a newer Rust version. Our current version is 1.80.0. Before using the next version, we will close those dependency update PRs and record them in this issue as a TODO item to avoid blocking Dependabot's functionality.

1.81

• build(deps): bump litemap from 0.7.4 to 0.7.5 #745
• bumps shadow-rs to 1.0.1 and adjust build.rs #731
