`docsrs_dep` is not a cfg attribute.

## `variadics_please` version

v1.1.0

## Relevant system information

This section is optional. Remove it if you know that the problem is not platform dependent.

Rust version you're using:

```text
cargo 1.93.0 (083ac5135 2025-12-15)
```

> Notes:
>
> - Pay attention to the msrv (minimum supported rust version) of `variadics_please`.
> - `nightly` should work, but sometimes there are regressions: please let us know!

Operating system, including version:

```text
NixOS 26.05.20251218.c6245e8
```

## What you did

When using the `#[doc(fake_variadic)]` feature, cargo emits the warning:

```text
warning: unexpected `cfg` condition name: `docsrs_dep`
--> golm/src/compiler_modules/syscall.rs:49:1
|
49 | / all_tuples!(
50 | | #[doc(fake_variadic)]
51 | | impl_into_syscall,
52 | | 1,
... |
55 | | p
56 | | );
| |_^

= help: expected names are: `docsrs`, `feature`, and `test` and 31 more
= note: using a cfg inside a macro will use the cfgs from the destination crate and not the ones from the defining crate
= help: try referring to `all_tuples` crate for guidance on how handle this unexpected cfg
= help: the macro `all_tuples` may come from an old version of the `variadics_please` crate, try updating your dependency with `cargo update -p variadics_please`
= note: see for more information about checking conditional configuration
= note: `#[warn(unexpected_cfgs)]` on by default
= note: this warning originates in the macro `all_tuples` (in Nightly builds, run with -Z macro-backtrace for more info)
```

## What went wrong

I think this cfg attribute may have been removed? I can't find anything about it outside of Bevy.
