This PR changes the following things in the docs workflow:
- Move from the deprecated actions-rs action to the maintained alternative of dtolnay https://github.com/dtolnay/rust-toolchain
- Instead of manually defining the cache paths and the cache keys, I moved to an action that handles this for us: https://github.com/Swatinem/rust-cache
- As github decided at some point that the generated `GITHUB_TOKEN` secret will only have read-only permissions (for new repos), unless you tell them to be different, I added the `permissions` key to the job. This will not affect this repository, but will affect e.g. new forks (the workflow will not throw an permissions error any more - Read more here: https://github.blog/changelog/2023-02-02-github-actions-updating-the-default-github_token-permissions-to-read-only/ )
This change was done as the v2 version still used the node v12 runtime.
This runtime is deprecated by github. There are no other breaking
changes done by the action. With the update to v3 now node v16 is used
as runtime.
You can read more about the changes from v2 to v3 here:

Adds support to the library for tokio 0.2 backward-compatibility. This should hopefully benefit, and prevent lavalink-rs from being blocked on this feature.
These can be reached using, e.g., `gateway-tokio-02`, `driver-tokio-02`, `serenity-rustls-tokio-02`, and `serenity-native-tokio-02` features.
Naturally, this requires some jiggering about with features and the underlying CI, which has been taken care of. Twilight can't be handled in this way, as their last tokio 0.2 version uses the deprecated Discord Gateway v6.
* Driver Benchmarks
Benchmarks driver use cases for single packet send,
multiple packet send, float vs opus, and the cost of
head-of-queue track removal.
Mix costs for large packet counts are also included.
This is a prelude to the optimisations discussed in
#21.
* Typo in benchmark
* Place Opus packet directly into packet buffer
Cleans up some other logic surrounding this, too. Gets a 16.9% perf improvement on opus packet passthrough (sub 5us here).
* Better track removal
In theory this should be faster, but it aint. Keeping in case
reducing struct sizes down the line magically makes this
faster.
* Reduce size of Input, TrackHandle
Metadata is now boxed away. Similarly, TrackHandles are neatly Arc'd to reduce their size to pointer length (and mitigate the impact of copies if we add in more fields).
