The "GroupRule" struct is missing the "limit" field.

[cuizhaoyue]

What happened?
I can't create a alerting rule with the "limit" field so that I can't limit the number of alerts an alerting can produce.

Did you expect to see something different?

How to reproduce it (as minimally and precisely as possible):

Anything else we need to know?:
the offical Prometheus is support the limit field in group_rule section.

The limit field is supported starting with Prometheus >= 2.31 and Thanos Ruler >= 0.24.
