Update platform010 & platform010-aarch64 symlinks

Summary:
`1.76.0` release with fixes addressing the following:
* Release notes ([link](https://releases.rs/docs/1.76.0/))
  * Most notable is [#118054](rust-lang/rust#118054) manifesting as:
```
error: unused implementer of `futures::Future` that must be used
   --> fbcode/mlx/metalearner/housekeeper/housekeeper.rs:213:13
    |
213 |             self.ping_oncall(&oncall, usecases);
    |             ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
    |
    = note: futures do nothing unless you `.await` or poll them
    = note: requested on the command line with `-D unused-must-use`
```
* Changes in `search_index.js` spec for `rustdoc` ([link](https://github.com/rust-lang/rust/pull/118910/files#diff-3ac57789ddcd2856a3b4f0c444f2813315179bdbe55bb945fe64fcb27b53fee5L491))
* Split of `#![feature(exposed_provenance)]` ([link](rust-lang/rust#118487)) from [#95228](rust-lang/rust#95228)
* `buck2` OSS toolchain bump to `nightly-2023-12-11` just before [#11878](rust-lang/rust-clippy#11878) and a bunch of other clippy lint renames.
