refactor(types): deduplicate AutomateParameters definition in automation types (#4522)

# Description of Changes

- Removed duplicate `AutomateParameters` interface from
`frontend/src/types/automation.ts`
- The interface was already defined earlier in the same file, leading to
redundancy
- Keeps type definitions consistent and avoids confusion
