fix: revert removal trim symbol before endif

[kurokobo]

SUMMARY

Closes #1713

By #1377, trim symbol (-) before endif was added. If we have defined ingress_annotations in one of the following way, this change will cause the spec for Ingress resource to break and the deployment to fail.

1. Defining ingress_annotations at the end of YAML file without trailing new line:

   ---
   spec:
     ...
     ingress_type: ingress
     ingress_hosts:
       - hostname: awx-demo.example.com
     ingress_annotations: |
       environment: testing⛔

2. Defining ingress_annotations as single line strings:

   ---
   spec:
     ...
     ingress_type: ingress
     ingress_hosts:
       - hostname: awx-demo.example.com
     ingress_annotations: 'environment: testing'

This PR restores the trim symbols that were removed in #1377.
