ref_as_ptr not available in Rust 1.77 despite documentation

[Rua]

Summary

The documentation for the ref_as_ptr lint says that it's available since Rust 1.77, but when I use it, I get a warning to say it's not.

Reproducer

I tried this code in Cargo.toml:

[lints]
clippy.ref_as_ptr = "warn"

This happened:

$ cargo clippy
warning[E0602]: unknown lint: `clippy::ref_as_ptr`
  |
  = help: did you mean: `clippy::ptr_as_ptr`
  = note: requested on the command line with `-W clippy::ref_as_ptr`
  = note: `#[warn(unknown_lints)]` on by default

The version in documentation indicates when the lint starts development.

so, in this case, this lint starts its development from nightly 1.77 but finally got merged on Feburary, which did not make it into rust stable yet...

Ah I see. A tiny bit confusing to say the least!

The version for ref_as_ptr was corrected to 1.78 in the last changelog (#12735) and is also available in 1.78 so I think we can close this.
