add a mention to the hardcoded relatives crate path

hello there 👋 😋

this plugin is very cool 👌 💪

❗ however, i have an error when trying to compile the source code as-is 🤔

> cargo build --release
error: failed to get `nu-json` as a dependency of package `nu_plugin_json_path v0.0.3 (/home/amtoine/.local/share/git/store/github.com/fdncred/nu_plugin_json_path)`

Caused by:
  failed to load source for dependency `nu-json`

Caused by:
  Unable to update /home/amtoine/.local/share/git/store/github.com/fdncred/nushell/crates/nu-json

Caused by:
  failed to read `/home/amtoine/.local/share/git/store/github.com/fdncred/nushell/crates/nu-json/Cargo.toml`

Caused by:
  No such file or directory (os error 2)

🔧 to fix it
as my repos are located in $env.GIT_REPOS_HOME/<host>/<owner>/<repo>, i had to run the following

>_ [nu-json nu-plugin nu-protocol]
))) | each {|crate|
)))     let local = ($env.GIT_REPOS_HOME | path join "github.com" "nushell" "nushell" "crates" $crate)
)))     cargo add $crate --path $local
))) }
      Adding nu-json (local) to dependencies.
             Features:
             + linked-hash-map
             + preserve_order
      Adding nu-plugin (local) to dependencies.
      Adding nu-protocol (local) to dependencies.
             Features:
             - plugin
             - serde_json

in the end, nothing bad at all, when the error is known it's straightforward to fix 😉

that's just a proposition with the newcomers in mind 😌

Thanks. I added your comments to the readme. I also removed nu-json because it isn't needed.

[amtoine]

amazing, that's perfect 👌

Absolutely cool plugin! I was able to install with no customization on the latest Macos.
Just fyi. 🙏🙏🙏
