Switch to form-based GitHub issue templates

This project provides the contributors with templates for the fundamental categories of issues:

- bug report
- feature request

This is helpful to the maintainers and developers because it establishes a standardized framework for the issues and
encourages the contributors to provide the essential information.

GitHub's original issue template system is very crude, simply pre-populating the issue description field with the text
from the template file.

https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/configuring-issue-templates-for-your-repository#creating-issue-templates

The contributor may be confused by being presented with a mass of Markdown and placeholder
content where they expected a field to write their issue. They also may find it inconvenient to manuever around the
framework content and replace the placeholder content.

A far better system is now available with GitHub's recently introduced form-based issue templates:

https://docs.github.com/en/communities/using-templates-to-encourage-useful-issues-and-pull-requests/configuring-issue-templates-for-your-repository#creating-issue-forms

The user is now presented with a web form. These may include multi-line input fields that have the same formatting and
attachment capabilities as the standard GitHub Issue composer, but also additional elements such as menus and checkboxes.

The use of this form-based system should provide a much better experience for the contributors and also result in higher
quality issues.
