Change PluginCommand API to be more like Command (#12279)
# Description

This is something that was discussed in the core team meeting last
Wednesday. @ayax79 is building `nu-plugin-polars` with all of the
dataframe commands into a plugin, and there are a lot of them, so it
would help to make the API more similar. At the same time, I think the
`Command` API is just better anyway. I don't think the difference is
justified, and the types for core commands have the benefit of requiring
less `.into()` because they often don't own their data

- Broke `signature()` up into `name()`, `usage()`, `extra_usage()`,
`search_terms()`, `examples()`
- `signature()` returns `nu_protocol::Signature`
- `examples()` returns `Vec<nu_protocol::Example>`
- `PluginSignature` and `PluginExample` no longer need to be used by
plugin developers

Plugin Example

Crate with a simple example of the Plugin trait that needs to be implemented in order to create a binary that can be registered into nushell declaration list

example config

This subcommand demonstrates sending configuration from the nushell $env.config to a plugin.

To register from after building nushell run:

register target/debug/nu_plugin_example

The configuration for the plugin lives in $env.config.plugins.example:

$env.config = {
  plugins: {
    example: [
      some
      values
    ]
  }
}

To list plugin values run:
