docs: fix decorator for @AfterRecover() (typeorm#9504)

### `@AfterRecover`

You can define a method with any name in the entity and mark it with `@AfterRecover`
and TypeORM will call it after the entity is recovered using repository/manager `recover`.
Example:

```typescript
@entity()
export class Post {
    @AfterRecover()
    updateStatus() {
        this.status = "recovered"
    }
}
```
`@AfterSoftRemove()` should be `@AfterRecover`
