feat: Simplify contribution template + pr scripts to run (strands-agents#221)

- Add a single script that runs the commands we want contributions to run.
 - Revamp the contribution template by:
    - Using HTML comments to guide the author, reducing the need to delete the text
    - Converting the type of change to be a flat list, allowing authors to delete all except the one they want
    - Updated the checklist items to allow items that are unnecessary to still be checked
