Description

Steps to Reproduce

I have a tinyint(1) type in mysql. I use sea-orm-cli v0.11.3
generate below: ```rust

use sea_orm::entity::prelude::*; use serde::{Deserialize, Serialize};

[derive(Clone, Debug, PartialEq, DeriveEntityModel, Eq, Serialize, Deserialize)]

[sea_orm(table_name = "dict")]

pub struct Model {

[sea_orm(primary_key)]

pub id: i64,
#[sea_orm(unique)]
pub key: String,
pub name: String,
pub is_pin: i8,
pub remark: String,
pub created_at: DateTime,
pub updated_at: DateTime,

}

[derive(Copy, Clone, Debug, EnumIter, DeriveRelation)]

pub enum Relation {}

impl ActiveModelBehavior for ActiveModel {}

3.  `is_pin` should be `bool`. but it is `i8`.

### Expected Behavior

<!-- What is expected to happen? -->
 `is_pin` should be `bool`.
### Actual Behavior

`is_pin`  is   `i8`.
<!-- What actually happened? -->

### Reproduces How Often

<!-- Is it always reproducible? -->
