chore: clean relative to references and borrows

- lint message: the borrowed expression implements the required traits

- 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
