Xen 4.20 release schedule proposal

[Oleksii Kurochko <oleksii.kurochko@xxxxxxxxx>]

Hello everyone,

Following the 8-month release cycle, also taking into account that 4.19
has been released 27.07.24 and the next "good" month for release should
be November according to [1] but it seems to me that it could be too short,
below is the proposed release schedule that I come up with for Xen 4.20.

Please don't hesitate to provide your feedback. 

If there are no objections, I plan to update the Wiki page Xen_Project_X.YY_Release_Notes to make it easier to find our final schedule ( especially for the people who aren't following xen-devel mailing list ). As an additional benefit, it will also be accessible via SUPPORT.md (in the wiki at https://xenbits.xen.org/docs/unstable-staging/support-matrix.html).

Thanks!

** Proposed option: Wed March 12, 2024 **
