Inconsistency in command format for edit command

[dhruvir29]

In some parts of the code, the command format is listed as such - "edit ENTRY_INDEX [n/NAME] [p/PHONE_NUMBER] [e/EMAIL] [a/ADDRESS] [nk/NEXT_KIN] [nkp/NEXT_KIN_PHONE] [fp/FINANCIAL_PLAN] [t/TAG]…​​". In other parts like the Summary at the end, the command format is listed as such - "edit ENTRY_INDEX [n/NAME] [p/PHONE_NUMBER] [e/EMAIL] [a/ADDRESS] [nk/NEXT_KIN] [nkp/NEXT_KIN_PHONE] [t/TAG]…​​". It might be good to standardise this so readers are not confused whether or not financial plan can be edited!
