os-server-groups API samples should indicate they are using microversion 2.64

[Matt Riedemann]

The samples in https://developer.openstack.org/api-ref/compute/#server-groups-os-server-groups are using microversion 2.64 but don't explicitly say that. The samples were changed in Rocky with change:

https://github.com/openstack/nova/commit/5cdb1ce26b0ec53c231723bcc6ce880aa8f43f0f

Normally when the API samples are using a microversion beyond 2.1, they put that into the description of the request/response samples, like this:

https://github.com/openstack/nova/blob/b046a998443d4586d4ca7a2863b785b909a4d076/api-ref/source/os-hypervisors.inc

Example List Hypervisors (v2.33): JSON response

So we'll want something like "(v2.64)" in the os-server-groups samples.

    Add microversion info in the os-server-groups API samples

    The os-server-groups samples are using 2.64 but don't explicitly say
    that, so we need something like "(v2.64)" in the os-server-groups.inc.

    In this patch, we add microversion info in the os-server-groups API
    samples.
