provider a func to check rule file like rulefmt.ParseFile in prometheus

[cruvie]

Is your proposal related to a problem?

I need to check a alert rule file, but when I use

import (
	"github.com/prometheus/prometheus/model/rulefmt"
	"testing"
)

func TestName(t *testing.T) {
	_, errors := rulefmt.ParseFile("./alerts1.rule")
	if errors != nil {
		t.Error(errors)
	}
}

error comes

[./alerts1.rule: yaml: unmarshal errors:
          line 1317: field partial_response_strategy not found in type rulefmt.RuleGroup]

it may relate to #1096 but I can only find a cmd tool.

Describe the solution you'd like

Why the CLI tool doesn't work for your usecase?
Or you can just follow https://github.com/thanos-io/thanos/blob/main/cmd/thanos/tools.go#L49C13-L49C13 and add your own function

I noticed the method, too, but I think if thanos changed prometheus' alert rule file, it should provider relate methods that prometheus contains like rulefmt.ParseFile

@cruvie Feel free to contribute if you think this is necessary for your usecase.
It should be pretty straightforward using existing code & functions.
