Can't write rules that are compatible with latest version of LogQL

[moustafab]

The expression validator doesn't support literals and doesn't recognize several of the newer query expressions from LogQL 2.X.

So far I've had a literal expression 1 (trying to use for a dead man's switch alert) fail for example. Also had issues with absent_over_time.

I think it probably needs an update to the Loki package and a couple of modifications to the expression parsing logic. I'd be happy to contribute a fix.

Unfortunately, the 2.x packages don't seems to being published: https://pkg.go.dev/github.com/grafana/loki/pkg/logql.

Therefor it currently a hacky way of keeping them up to date.

Release v0.6.0 which is updated with logql v2.3.0.
Please let me know if this works for you.
