Subject: [PATCH] Add env-conversions helpers to std (#15569)

When combined with [the Cookbook
update](https://github.com/nushell/nushell.github.io/pull/1878), this
resolves #15452

# Description

When we removed the startup `ENV_CONVERSION` for path, as noted in the
issue above, we removed the ability for users to access this closure for
other purposes. This PR adds the PATH closures back as a `std` commands
that outputs a record of closures (similar to `ENV_CONVERSIONS`).

# User-Facing Changes

Doc will be updated and users can once again easily access `direnv`

# Tests + Formatting

- :green_circle: `toolkit fmt`
- :green_circle: `toolkit clippy`
- :green_circle: `toolkit test`
- :green_circle: `toolkit test stdlib`

# After Submitting

Doc PR to be merged when released in 0.104
