chore: test keystore against nwaku

[danisharora099]

Description

Now that we have Keystore generation and management, we would like to validate that this Keystore actually works against prod nwaku codebase to run a node.

The issue tracks the work around validating this Keystore against the nwaku codebase.

Since nwaku isn't ready with the new RLN v2 contract upgrade integrated in the codebase yet, there is a draft PR to test against: logos-messaging/logos-messaging-nim#3390

Resolved with the candidate harbor.status.im/wakuorg/nwaku:v0.36.0-rc.0
