fix: add frame-support-procedural

[chungquantin]

Without the dependency, got an error with frame-support when run cargo test --release on the example contract:

error[E0433]: failed to resolve: could not find `try_runtime_enabled` in `frame_support`
   --> /Users/chungquantin/.cargo/registry/src/index.crates.io-6f17d22bba15001f/frame-system-36.1.0/src/lib.rs:257:1
    |
257 | #[frame_support::pallet]
    | ^^^^^^^^^^^^^^^^^^^^^^^^ could not find `try_runtime_enabled` in `frame_support`
    |
    = note: this error originates in the attribute macro `frame_support::pallet` (in Nightly builds, run with -Z macro-backtrace for more info)

How to reproduce?

Remove the Cargo.lock (if you have that for the example contract) and run cargo test --release on the example contract.

cargo update -p frame-support-procedural --precise 30.0.1 can fix the error.

@zjb0807 Yes that is what this PR does.

@zjb0807 Yes that is what this PR does.

I means this:

rm Cargo.lock
cargo test --release

cargo update -p frame-support-procedural --precise 30.0.1
cargo test --release

only update the Cargo.lock will fix the error.
