feat: add option to support git push with -f about hub-mirror-action

[Yikun]

@Ir1d thanks for you feedback, and I will add this feature soon (maybe in this week).

and looks like we could add a force_update input arg, and default is false, and if user want to push with -f flag, he can use something as below:

- name: Mirror with force push (git push -f)
  uses: Yikun/hub-mirror-action@master
  with:
    src: github/Yikun
    dst: gitee/yikunkero
    dst_key: ${{ secrets.GITEE_PRIVATE_KEY }}
    dst_token: ${{ secrets.GITEE_TOKEN }}
    force_update: true

@Yikun Thanks, really looking forward to this feature.

@Ir1d Hi, I add the force update support in v0.08, that means you could use the master or v0.08 version to have a try.

It would be good if you could try it and give some feedback in here, thanks!

I think its working perfectly, thanks!
