Create a pull-request template

[zepfred]

The goal is to create a standardized process for updating quickstart modules and a pull request (PR) template that includes checkbox fields that must be marked before submitting or merging a PR. Here are some examples:

1. Does the proposed change, if needed, incorporate tests to prevent any regressions?
2. Are the UI and JS files fully tested?
   • Did you check all UI buttons (E.g., solve and analyze buttons)?
   • Did you check the network calls?
   • Did you check the console messages?
3. Do you have a green build?
