fix(feature/specta): Resolve error when using latest version of specta with tauri specta feature

[johncarmack1984]

Presently, when running tauri dev with the specta feature enabled, the terminal shows this error:

error[E0433]: failed to resolve: use of undeclared crate or module `specta_util`
   --> ~/.cargo/registry/src/index.crates.io-6f17d22bba15001f/tauri-2.1.1/src/plugin.rs:911:39

    |
    = note: this error originates in the derive macro `specta::Type` (in Nightly builds, run with -Z macro-backtrace for more info)

By upgrading to the latest specta version and adding the specta-util package to the feature, functionality is restored to expected behavior.

Notes:

• cargo test has the same outcome on this branch as it does on dev branch (1 failed)
• Same for cargo clippy (1 warning)

Let me know if anything else is needed!

Per @FabianLars via #11872, requesting that whoever reviews this PR might ignore the failing lint, since the fix for the lint is present in #11694

note that the specta_util explicit reference was removed recently
https://github.com/specta-rs/specta/pull/294/files#diff-3014e445edf11c74bdfdb0601494abf5d22f01c14214d203b86768d00dda2d36L42
so when specta releases its next version, we'll be able to remove the specta_util dependency
