Minimal perspective component 8.1 example needs to be updated to account for Jetty 12 package paths

See this forum thread:

I think either the module's minimum Ignition version needs to be bumped or we need to comment out/change the import used in the gateway hook override:
https://github.com/inductiveautomation/ignition-sdk-examples/blob/276f89239073e2108253716bce7f4ff70d20698d/perspective-component-minimal/gateway/src/main/java/io/ia/example/perspective/min/gateway/OneComponentGatewayHook.java#L71-L74

Start with perspective-component-minimal/gateway/src/main/java/io/ia/example/perspective/min/gateway/OneComponentGatewayHook.java at lines 71-74 and review the linked forum thread for the Jetty 12 package-path issue. Determine whether the minimum Ignition version should change or the gateway hook import should be updated. Done means the 8.1 example uses the correct Jetty 12 paths and no longer has the reported compatibility problem.
