Bug: node-fetch used by squid-sdk/util/util-internal-http-client is not compatible with node 20

This error was noticed, but it seems not critical (Affecting the log module only), and the processor is functioning without noticeable issues.

The original issue seems to be thrown by node-fetch. squid-sdk firesquid release uses a version that is not compatible with node 20. firesquid uses node 16.

We recently tried to use node 20 which triggered this issue, so reverting to node 18 should make this error in logs gone.
