395be442 - Implement `uv pip show` (#2115)

Implement `uv pip show` (#2115) ## Summary Implementation for https://github.com/astral-sh/uv/issues/1594 The output will contain only the name, version and location of the packages for now but it should be extendable to include other information in the future. Quite inexperienced with Rust, so please forgive me if there are things that obviously don't make sense 😭 ## Test Plan Added a bunch of unit tests. The exit code behavior matches `pip`'s behavior: - When the package is found -> exit code 0 - When the package isn't found -> exit code 1 - When one package is found but another isn't -> exit code 0
