I have some doubt about these changes, so I keep it as a undocumentated features so far. Basically, I change the name of the following decorators from Marshamallow:

• validates -> validate
• validates_schema -> validate_schema
• pre_load -> before_load
• post_load -> after_load
• pre_dump -> before_dump
• post_dump -> after_dump

Some ideas behind these changes:

• validate and validate_schema are short and clear than validates and validates_schema. It also matches the validate keyword in field classes.
• The change from pre_ to before_ and from post_ to after_ was trying to follow the name convention in Flask (before_request, etc.).

IMO, the new names are easier to understand and intuitive. However, this will definitely introduce "breaking" changes between APIFlask and Marshmallow. I can add a warning in the docs to inform users that they can continue to import everything from marshmallow, but notice the name changes if they want to import from APIFlask.

Is it a good or bad idea? Feel free to leave any thoughts.
