Repository Default Files

[DavidLambauer]

We could include some very classy default files in most of the repos. Damian uses good ones for issue templating, for example.

For mageos-* repos (so the source of our distribution), we should also add the .github/workflows/merge-upstream-changes.yml action.

Reference:
https://github.com/mage-os/mageos-magento2/blob/2.4-develop/.github/workflows/merge-upstream-changes.yml

Currently this is missing in a number of repos:

• https://github.com/mage-os/mageos-magento-zend-log
• https://github.com/mage-os/mageos-magento-zend-exception
• https://github.com/mage-os/mageos-magento-zend-cache
• https://github.com/mage-os/mageos-magento-zend-pdf
• https://github.com/mage-os/mageos-magento-zend-loader
• https://github.com/mage-os/mageos-magento-zend-db
• https://github.com/mage-os/mageos-magento-zend-memory
• https://github.com/mage-os/mageos-magento-coding-standard
• https://github.com/mage-os/mageos-composer
• https://github.com/mage-os/mageos-magento2-functional-testing-framework
