Improve dependency version requirements

[ranger-ross]

This library current specifies the minor version for validation and garde but since those libraries are both pre 1.0 this will require this library to update when they update.

See https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html#tilde-requirements

I tested with garde and the tilde version requirements still caused issues. I probably need to do some more research on the best practices for this.
