chore: clean relative to references and borrows

- lint message: the borrowed expression implements the required traits
help: for further information visit https://rust-lang.github.io/rust-clippy/rust-1.92.0/index.html#needless_borrows_for_generic_args
- lint message: this expression creates a reference which is immediately dereferenced by the compiler

- remove useless taken reference
lint message: needlessly taken reference of left operand

- use &Path instead of &PathBuf as fn parameters
lint message: writing `&PathBuf` instead of `&Path` involves a new object where a slice will do
