API: Make the "Sensitive Files" GitHub Action more robust

[palisadoes]

Is your feature request related to a problem? Please describe.

1. Our pull request GitHub action has a section that detects and fails when sensitive files are found to be submitted during PRs
   1. https://github.com/PalisadoesFoundation/talawa-api/blob/develop/.github/workflows/pull-request.yml
2. If the required GitHub label is applied the test is skipped
3. The test only works when a new commit is submitted, and not when the test is re-run
4. The list of files is a string

Describe the solution you'd like

1. Make the list of files in the GitHub action a list.
2. Modify the test to work when both a new commit is submitted and also when the test is re-run
3. Test this GitHub action in your own repository before submitting your PR

Additional context

1. Test this GitHub action in your own repository before submitting your PR
2. This has already been implemented in Talawa-Admin. Use the YAML from the PR for this issue and update the SENSITIVE_PATTERNS variable to match the needs of this repository.
