fix(charts): fix the service name used by the helm test

[WillerWasTaken]

What

Fix the helm test command when installing airbyte.
The created test pod airbyte-test-connection fails with the error

wget: bad address 'airbyte-webapp:80'

How

The pods is doing a wget against the webapp service as seen in the pod description.
There seems to be a mismatch between the service name used in the test and the one declared in the webapp chart.

Using the same name in both places should resolve the current issue when using helm test
