Convert issue templates in markdown to Github's issue forms

[mitchelbaker-cisa]

💡 Summary

GitHub has a beta feature that adds forms to issues. YAML syntax is used to build the layout which makes converting from our markdown templates for bug/idea submissions straight forward. Note that issue forms are not yet supported for pull requests.

This issue would be useful because forms encourages specific, structured information we want included in issues, as well as required fields and validation.

Implementation notes

• Create a YAML form definition file in the ./.github/ISSUE_TEMPLATE directory
• Discuss with team on what information should be included, required fields, etc.
