The Big POS Typescript SDK

/* 
  This script is meant to run after the SDK has been generated.

  - It updates the generated code to ensure that all PATCH methods use ContentType.JsonPatch.
  - It also ensures that the ContentType enum includes JsonPatch and modifies the Operation interface
    to allow any value for the `value` property instead of just object or null.

  This is necessary because the SDK generation does not currently handle these cases correctly.
