test (e2e) : change nodeport service access in jkube e2e test (#4683)

[rohanKanojia]

Description

Fixes: #4683

Relates to: #4636

Usage of unix style variables to store temporary command results isn't working on windows. Execute the same steps using golang code in order to make check platform independent.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• Feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to change
• Chore (non-breaking change which doesn't affect codebase;
  test, version modification, documentation, etc.)

Proposed changes

Remove the steps involving setting/evaluating unix style variables and add a custom step to extract NodePort and crc machine ip and hit the endpoint.

Testing

I've tested it on my windows machine to verify test is still passing after making changes
