    rust: Update rust crates
    
    Update (cargo update) the rust crates for wasm-wasi-component, otel &
    unitctl.
    
    This will fix build issues with wasm-wasi-component & rustc 1.86+.
    It will also fix dependabot issues in otel and unitctl.

Yeah, looks like we're hitting the exact issue on homebrew that has a newer Rust version: https://github.com/nginx/homebrew-unit/actions/runs/14298398297/job/40216705842

Also, this will make us depend on Rust 1.83+ afaict...

[ac000]

Such is rust life...

[ac000]

And now this is also failing... fsck... remind me again who said rust was a good idea?!

@thresheek Feel free the approve this PR!

[ac000]

Although this new failure is from building wasmtime from source... is it bundling an old version of the problematic crate?
Not to emntion there's a bunch of other warnings when building it.

Either way, not sure why we're bothering to build it from source here...

[ac000]

Seeing if bumping wasmtime to 31.0.0 in pkg/contrib fixes things...

[thresheek]

I think we need to bump wasmtime in both pkg/contrib and src/wasm-wasi-component/Cargo.toml stuff - since https://github.com/nginx/unit/actions/runs/14362591784/job/40267665156?pr=1591 fails the similar way

That said, maybe other crates need a bump in Cargo.toml too.

[ac000]

Indeed, building wasmtime 31.0.0 is warning and error free...

This PR updates all crates in src/wasm-wasi-component, src/otel and tools/unitctl.

This PR bumps pkg/contrib/src/wasmtime to 31.0.0

[ac000]

Note: The important bit to update was wit-parser, wasmtime must come with it bundled.

[ac000]

However, while this PR obviously fixes the wasm-wasi-component build, I'm not sure why the wasm test isn't failing with the wamtime build, which while having the compilation warnings doesn't have the compilation error that we are now seeing elsewhere... strange... anyway between this and the other PR it should be all good...

I think the ubuntu-latest runners just had a software bump, which probably explains what we've been seeing:

E.g. https://github.com/nginx/unit/actions/runs/14362591784/job/40267664555?pr=1591 was picked up by:

  Image: ubuntu-24.04
  Version: 20250406.1.0
  Included Software: https://github.com/actions/runner-images/blob/ubuntu24/20250406.1/images/ubuntu/Ubuntu2404-Readme.md

Which seems to have Rust 1.86.0

While https://github.com/nginx/unit/actions/runs/14335337085/job/40180839867?pr=1588 was picked up by an older version:

  Image: ubuntu-24.04
  Version: 20250323.1.0
  Included Software: https://github.com/actions/runner-images/blob/ubuntu24/20250323.1/images/ubuntu/Ubuntu2404-Readme.md

Which had Rust 1.85.1.

Err, wrong first job URL, but I think that doesnt really matter much.
