[QA] Validate DateTime properties in json schema

[amrita-shrestha]

Describe the bug

Our current test framework only verifies the presence of date-related properties in the response but does not validate the correctness or format of those date-related properties.

For example, consider the following step:
And the JSON data of the response should match

• lastModifiedDateTime
• takenDateTime
• expirationDateTime
• createdDateTime

Task

Research and implement a method to validate the accuracy and format of dateTime values in the response.
