This PR changes `$env` to be **case-preserving** instead of case-sensitive. That is, it preserves the case of the environment variable when it is first assigned, but subsequent retrieval and update ignores the case. Notably, both `$env.PATH` and `$env.Path` can now be used to read or set the environment variable, but child processes will always see the correct case based on the platform. Fixes #11268. --- This feature was surprising simple to implement, because most of the infrastructure to support case-insensitive cell path access already exists. The `get` command extracts data using a cell path in a case-insensitive way (!), but accepts a `--sensitive` flag. (I think this should be flipped around?) |

nu-protocol
The nu-protocol crate holds the definitions of structs/traits that are used throughout Nushell. This gives us one way to expose them to many other crates, as well as make these definitions available to each other, without causing mutually recursive dependencies.
