cargo-udeps: pin nightly version to fix "unknown feature stdsimd" error

[Bravo555]

Proposed changes

Pin nightly version so cargo-udeps keeps working. After our dependencies are updated and don't use the incompatible ahash version, the pin can be removed.

Types of changes

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Improvement (general improvements like code refactoring that doesn't explicitly fix a bug or add any new functionality)
• Documentation Update (if none of the other choices apply)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)

Paste Link to the issue

• cargo-udeps fails due to compilation error of ahash crate #2686
