[Feature] Migrate features to Gitee

[frank-zsy]

Description

As we support Gitee data and support multiple platforms(#892 ) now, we can start to migrate features to Gitee.

First we may start to adopt activity, openrank and contributors/participants charts to Gitee repos.

Next, I will follow up on this issue.

In December, due to issues with paper acceptance, participation in competitions, and learning, no progress was made on this matter. Now these things are gradually coming to an end, and I will start pushing forward with this task.

It's best to establish a goal plan. Through time planning, we can better arrange things.

Two time points, before the start and end of the next semester.

• Complete the infrastructure renovation before the project migration starts next semester. In this way, when it comes to the migration of specific functions, everyone can imitate existing functions. In this way, whether it is a course task or a daily task, anyone who wants to participate can join and divide it into small functional tasks for everyone to complete.
• Complete the overall functional migration before the end of next semester.

Of course, this plan is just a plan. Being able to complete it is the best. The time left should still be quite ample.
