[Validation][Workflow] Automate data validations

[ChanukaUOJ]

Problem

• The current manual data validation is time consuming because there are a lot of data there. For an example, if any tabular data changed in a data.json file, we need to manually check the Column_count and Row_count in the metadata.json file related to that data. This can be automated through a workflow to minimize the time taken to check this manually when the PR is made.
• Also this can be expanded when the data scales by adding other validations as well
