fix(hoppscotch): auto generated whitelist app origin not formatted correctly

[jonathanfoster]

What Happened

I installed hoppscotch-0.1.0 and the Hoppscotch Desktop app was unable to connect to this instance. The issue is caused by a bug in the logic for auto generating whitelist origins. The whitelisted origin for the desktop app was app://hoppscotch.example.com and the actual desktop app origin is app://hoppscotch_example_com.

Expected Behavior

The Hoppscotch Desktop app should be able to connect to a hoppscotch-0.1.0 instance without additional configuration. The auto generated app whitelist origin must replace . with _ when formatting the desktop app origin.

Steps to Reproduce

1. Install hoppscotch-0.1.0:

   helm install hoppscotch charts/hoppscotch -n default --values=charts/hoppscotch/ci/default-values.yaml --create-namespace --wait 

2. Verify incorrect desktop app origin (i.e., app://hoppscotch.local instead of app://hoppscotch_local):

   $ kubectl get configmap hoppscotch -o yaml | grep WHITELISTED_ORIGINS
     WHITELISTED_ORIGINS: https://hoppscotch.local,app://hoppscotch.local

3. Start desktop app and attempt to add hoppscotch-0.1.0 instance

Temporary Workaround

You can specify the whitelisted origins explicitly to workaround this bug.

hoppscotch:
  backend:
    whitelistedOrigins:
      - https://hoppscotch.local
      - app://hoppscotch_local
