Add more example content for good software development practice

Builds on @bilalshaikh42's suggestions:

• GitHub actions
  • Semantic versioning and automated release notes
  • Static code analysis (e.g., OSSAR)
  • Dependency management (whitesource)
  • Spell checking
  • Sensitive data (GitGuardian)
  • Semantic commits (amannn/action-semantic-pull-request)
  • Format source code
• Citation file
• GitHub issue template
• GitHub PR template
• GOVERNANCE.md

While this would be helpful for some, we should keep in mind that a large template repo with many files can appear intimidating. It makes it appear like developers need to create a large amount of content, when in fact much of the files just required replace a few placeholders with the name of the simulation tool, list of developers, URL for home page, etc.

We could consider having a second, more minimal template, with just the required content without extra recommendations.

We can also use this tool to generate files for users based on simple CLI questions

That's a nice suggestion.
