### Clap Version

4.0.7

### Describe your use case

I was looking for a way to skip a variant from an enum, when using the `ValueEnum` derive macro. Turns out there actually IS a way, but it's not mentioned anywhere in the reference in a direct way.

Simple example:
```rust
#[derive(Debug, ValueEnum)]
struct Format {
    Text,
    Json,
    #[value(skip)]
    None, // handled by another flag manually
}
```

The `hide` attribute is mentioned (somewhat), as one can check the available functions on the `PossibleValue` struct, but it's not the same as it only hides it in the docs. Only with `#[value(skip)]` it's fully omitted and becomes an impossible value to create through the CLI.

The `skip` attribute is only mentioned in a few places in the derive reference:
- In the command attributes, as part of the `Subcommand` specific attributes: https://docs.rs/clap/4.0.7/clap/_derive/index.html#command-attributes
- In the arg group attributes: https://docs.rs/clap/4.0.7/clap/_derive/index.html#arggroup-attributes
- In the arg attributes, but only for typical fields and saying that it uses `Default::default()` or the given expression, so it doesn't look applicable for enums: https://docs.rs/clap/4.0.7/clap/_derive/index.html#arggroup-attributes
- The overview talks about skipping of non-unit enum variants, but doesn't tell how: https://docs.rs/clap/4.0.7/clap/_derive/index.html#overview

### Describe the solution you'd like

There is already a `ValueEnum` section for attributes in the docs: https://docs.rs/clap/4.0.7/clap/_derive/index.html#valueenum-attributes

This one only needs an additional entry for the `skip` attribute, describing that it can be used to omit variants from the generated implementation.

<!--
Thanks for helping out!

Please link the appropriate issue from your PR.

If you don't have an issue, we'd recommend starting with one first so the PR can focus on the
implementation (unless its an obvious bug or documentation fix that will have
little conversation).
-->
Documenting the `skip` attribute for the `ValueEnum` derive macro promptly, as it's not mentioned anywhere else.

Fixes #4327
