fix: Updated test case outputs and fuzzy assertion

[chandrasekharan-zipstack]

What

• Updated some test case outputs for all tests to pass
• OCR related tests are asserted with a fuzzy match rather than a strict match with a confidence threshold of 97%

Screenshots

• Tests passing
  
• Examples of failures in fuzzy assertion
