[Bug]: Fix wait package timeout error message

[mrhillsman]

Description

Two tests in wait_test.go expect error messages containing "timed out" but the ErrVMTimeout constant uses "timeout waiting for VM".

Steps to reproduce

go test -v ./internal/wait/... -run "timeout"

Expected: Tests pass
Actual: Tests fail because "timeout waiting for VM" does not contain substring "timed out"

Fix

Change ErrVMTimeout message from "timeout waiting for VM" to "timed out waiting for VM"

Affected file

internal/wait/wait.go:18
