Create GitHub Action to Import Database for PR Testing

[palisadoes]

Describe the bug

1. Running the command npm run import:sample-data fails
2. This is due to an update in the DB schema which is not compatible with our sample data
3. We also don't have the ability to automatically test the command as part of our PR approval process

To Reproduce

Steps to reproduce the behavior:

1. Run npm run import:sample-data
2. Failure

Expected behavior

1. The sample data must be modified to accommodate the new DB schema where the userRegistrationRequired field now replaces the isPublic field. The logic of userRegistrationRequired is opposite of isPublic therefore True will replace False and vice versa for these fields in the data update.
   1. Data importation must succeed without error
2. A GitHub must be created to import the data as part of the PR YAML file.
   1. https://github.com/PalisadoesFoundation/talawa-api/blob/develop/.github/workflows/pull-request.yml
   2. This must occur after running the test suite and before the code coverage is calculated
   3. The GitHub action pass this stage of the workflow

Actual behavior
