Fix warning: remove unnecessary .clone()

[sigurpol]

Fix the following warning in patches.rs:

warning: call to `.clone()` on a reference in this situation does nothing
   --> src/patches.rs:119:66
    |
119 |                       .ok_or("Unable to get path from toml Value")?
    |  __________________________________________________________________^
120 | |                     .clone(),
    | |____________________________^ help: remove this redundant call
    |
    = note: the type `str` does not implement `Clone`, so calling `clone` on `&str` copies the reference, which does not do anything and can be removed
    = note: `#[warn(noop_method_call)]` on by default

By removing the ⁠.clone(), the code becomes more efficient as it avoids an unnecessary string allocation and copy. ⁠

@kianenigma , since you mentioned the existence of this fork in our 1:1 yesterday or @seadanda since you have introduced me to the beauty of cargo remote in your onboarding doc... maybe you want to have a look. Pretty pointless, I know 😅

Caching update seems fine to me too
