Bootstrap Errors from Rust Clippy

[ryan-moreno]

Describe the bug

Running bootstrap.ps1 results in errors that prevent the simulators from being built properly. This appears to be related to a new release of rust clippy adding new warnings.

To Reproduce

Clone qsharp-runtime repo
Install listed pre-requisites and Powershell 7
Run boostrap.ps1

Expected behavior

boostrap runs without errors

Actual behavior

Errors from rust clippy (pasted below)

System information

OS: Windows
rustc/rust-clippy version: 1.55.0

Thanks for filing this, @ryan-moreno! It looks like cargo clippy recently added a few new checks, but our build has clippy warnings promoted to errors by default. Thankfully, the six new linting issues are pretty straightforward to resolve, so let me go do that. Thanks!
