Fix issue with whitespace in ADML data

[twangboy]

What does this PR do?

Fixes an issue with the text field in ADML data containing an extra space at the end.

This happens with the Legacy Templates from Microsoft. The KeepAliveTime value of 300000 or 5 minutes (recommended) has a space at the end. This causes states to report that a change is needed when in fact it the policy is already set.

MSS_KeepAliveTime:
  lgpo.set:
    - computer_policy:
        "MSS: (KeepAliveTime) How often keep-alive packets are sent in milliseconds":
          "KeepAliveTime": '300000 or 5 minutes (recommended)'

When the state does the comparison it is comparing the requested dict:

{'KeepAliveTime': '300000 or 5 minutes (recommended)'}

with the current setting

{'KeepAliveTime': '300000 or 5 minutes (recommended) '}
