🔥 refactor(benchmarking.rs): Update benchmarking setup for pallet-template

🔥 refactor(lib.rs): Remove migrations module and v2 migration file
The benchmarking setup for the pallet-template has been updated to use the `frame_benchmarking::v2` module instead of `frame_benchmarking::{benchmarks, whitelisted_caller}`. This change improves compatibility with the latest version of the frame_benchmarking crate.

The migrations module and v2 migration file have been removed as they are no longer needed. The v2 migration logic has been integrated into the main pallet module, eliminating the need for a separate migrations module. This simplifies the codebase and improves maintainability.
