chore: remove server.host option for e2e test

[Dunqing]

Description

An edge case I encountered. Ports 5173 are occupied by another vite server that uses the server.host option by default. When I run pnpm test-serve, the test server will listen() successfully. Normally it should fail and then start port 5174 but it doesn't.

I noticed server.host = true in e2e test, so the host is undefined. According to the documentation described as follows

If host is omitted, the server will accept connections on the unspecified IPv6 address (::) when IPv6 is available, or the unspecified IPv4 address (0.0.0.0) otherwise.

So the http server may not listen to localhost. maybe 192.168.xx.xx or else.

The solution to this issue is easy, just use network[0] instead of local[0] will work

I came across this problem quite a few times, too! Glad to see that it can be fixed!

Maybe we can remove the host: true config altogether? Seems to be added in #2977 but even if I removed it, it still seem to work.

Yes. I'm fine with either solution.
