proposed 7.1 release schedule

[Peter Maydell]

I just put some proposed dates into the 7.1 schedule page:
https://wiki.qemu.org/Planning/7.1#Release_Schedule

* 2022-07-12  Softfreeze
* 2022-07-19  Hardfreeze. Tag rc0
* 2022-07-26  Tag rc1
* 2022-08-02  Tag rc2
* 2022-08-09  Tag rc3
* 2022-08-16  Release; or tag rc4 if needed
* 2022-08-23  Release if we needed an rc4

Does this work for people? I just worked backwards
from a final release date about 4 months after 7.0; easy
enough to shift it forward or back by a week or so if
that works better for some reason.

thanks
