feat(rate_limit): updating redis crates and optimizations

[geekbrother]

Description

This PR updates the rate_limit crate with the following changes:

• Updates deadpool_redis dependency to the latest 0.22;
• Updates redis client to the latest 0.32;
• Optimization in the token_bucket_many function by reusing the lua script instance instead of hashing it on every call;
• Minor optimizations in the Lua token bucket script to cache the redis call, remove double calculation, and remove ipairs in a loop.

This PR fixes the Rust version in the CI fmt check job to use stable to be the same version as in the clippy job.

Formatting fixes for an updated Rust version to fix Clippy errors.

How Has This Been Tested?

Rate limiter unit tests were passed when tested on a local Redis instance.

Due Diligence

• Breaking change
• Requires a documentation update
• Requires a e2e/integration test update
