[CHANGE] Create Orm alias decorator for MikroORM

[Romakita]

Information

• Version: 6.x
• Packages: @tsed/mikro-orm

The Mikro orm author suggest to change the @Connection decorator to another one. I suggest to create the Orm decorator to replace the Connection.

See mikro-orm/mikro-orm#2587

Example

import {Injectable, AfterRoutesInit} from "@tsed/common";
import {Connection} from "@tsed/mikro-orm";
import {MikroORM} from "@mikro-orm/core";

@Injectable()
export class UsersService {
-  @Connection()
+ @Orm() 
-  private readonly connection!: MikroORM;
+  private readonly orm!: MikroORM;

  async create(user: User): Promise<User> {

    // do something
    // ...
    // Then save
-    await this.connection.em.persistAndFlush(user);
+    await this.orm.em.persistAndFlush(user);
    console.log("Saved a new user with id: " + user.id);

    return user;
  }

  async find(): Promise<User[]> {
    const users = await this.orm.em.find(User, {});
    console.log("Loaded users: ", users);

    return users;
  }
}

Acceptance criteria

• @Connection is deprecated with the Js doc comment: @deprecated Since 2022-02-01. Use Orm decorator instead.
• @Orm decorator have the code implementation. Connection will just call the Orm one.
• Documentation is up to date
