Add vite address to webmock allowed hosts
What does this MR do and why?
If a developer's GDK is configured to run on a host other than 127.0.0.1
webmock will intercept requests to Vite when running feature specs and raise this error:
WebMock::NetConnectNotAllowedError:
Real HTTP connections are disabled. Unregistered request: GET http://172.16.123.1:3038/vite-dev/javascripts/entrypoints/tracker.js with headers ...
This change modifies the webmock config to explicitly allow the configured host address for Vite if it's enabled.
