Only inform about updates that affect current node network variant

[Neotamandua]

Summary

Some nodes are receiving information about a new version of the node installer being available, even though this version is intended for e.g., the testnet. Updating does nothing.

Possible Solution (optional)

Update the version check logic to be network-aware (devnet, testnet, mainnet), so that version notifications are only shown when a newer release is available for the node network variant.

[HDauven]

Instead of doing a version check on the node-installer release, it should version check on the per network rusk component, based on the network configured. We can figure out the configured network in multiple ways, including leaving some metadata on the local machine, or by looking up the available configs, or the chain ID provided by the node.
