The toml workflow job will now install taplo-cli using cargo-binstall (#18773)

# Objective
Avoid needing to compile `taplo-cli` every time we use it in CI.

## Solution
Use [cargo-binstall](https://github.com/cargo-bins/cargo-binstall) to
install `taplo-cli`.

cargo-binstall is different from `cargo install`, in that it will first
attempt download a precompiled `taplo-cli` binary, in an attempt to
avoid compilation. However, failing that (for any reason), it will fall
back to installing the binary through `cargo install`.

While installing `taplo-cli` from source is relatively fast (around
50-60s), this still provides a small speed boost to the job, by not
needing to spend time compiling `taplo-cli` from source at all.

## Note on how this affects workflows
This PR does have one side-effect: Should `taplo-cli` need to be
compiled from source at all, it is no longer guaranteed to use the
latest `stable` version of `rustc`. This may be considered problematic,
as `taplo-cli` doesn't appear to have a MSRV policy.

However, its MSRV (as of writing this PR) is `1.74` - a nearly 1.5 year
old version. This seems to imply that, if `taplo-cli`'s MSRV is ever
updated, it won't be to the absolute latest stable version of Rust until
said version is a few months old.

Combine that with [the Github Actions runner images being frequently
(and automatically) updated to use the latest Rust
tooling](https://github.com/actions/runner-images/pull/11957), and I
don't foresee `taplo-cli`'s MSRV being an issue in 99% of circumstances.

Still, there is the possibility of it being a problem in those 1% of
circumstances - if this is a concern, please let me know and I'll try to
fix it.
