Added model validation to remove UNSET before field validation (#1233)
* Add model validation to remove UNSET before field validation

Updated aiogram/types/base.py to include a model validator which removes any 'UNSET' before field validation. This change was necessary to correctly handle `parse_mode` where 'UNSET' is used as a sentinel value. Without the removal of 'UNSET', it would create issues when passed to model initialization from `Bot.method_name`. 'UNSET' was also added to typing. Tiny documentation fix was made.
