Add acoount type support

[Yikun]

Current, only org account type repo sync is supported, but the user account type is not suported.

We can add an is_org (False by default) add a account_type (can be set to user or org, user by default) to get/list the repos from user account or org account.

The org sync：

steps:
- name: Mirror the Github organization repos to Gitee.
  uses: Yikun/hub-mirror-action@master
  with:
    src: github/kunpengcompute
    dst: gitee/kunpengcompute
    dst_key: ${{ secrets.GITEE_PRIVATE_KEY }}
    dst_token:  ${{ secrets.GITEE_TOKEN }}
    account_type: org

The user sync：

steps:
- name: Mirror the Github organization repos to Gitee.
  uses: Yikun/hub-mirror-action@master
  with:
    src: github/xxx
    dst: gitee/xxx
    dst_key: ${{ secrets.GITEE_PRIVATE_KEY }}
    dst_token:  ${{ secrets.GITEE_TOKEN }}

Now you can use the account_type to specify the repo account type (org or user).
