Metrics from @layer0/rum is prefetching wrong URL

[thehansys]

Hello,
I have created a new NextJS app with @layer0/rum package and I am facing an issue with cache-manifest.js file when I run my app on localhost. The problem is that the rum package adds prefetch link with the wrong URL (/__xdn__/cache-manifest.js) which doesn't exists and returns 404 error.

Here's the repo of created app with the steps how to preproduse the issue. It's just plain NextJS app with @layer0/rum package.

It seems that the problem is caused by if condition on line 115 in https://github.com/layer0-platform/rum/blob/main/src/Metrics.ts file.
When I use 127.0.0.1 address instead of localhost everything works fine.
