Add Issue and PR Templates

[ashstewart7]

What issue is this solving?

Closes #4

Description

Adds templates for:

• Creating a bug report based issue
• Creating a feature request based issue
• Creating a PR

GitHub has (since creating templates on the old project) implemented a new way of having issue templates through YAML defined forms. This seems neat so I've implemented them here, but am happy to backtrack and use the old MD-style if desired. Given the decreased flexibility of these in certain situations, I've enabled the option to override and create a blank issue if we ever need it.

PR still uses old format, due to the YAML form syntax not being supported here.

Any helpful knowledge/context for the reviewer?

• Any new dependencies to install? ❌
• Any special requirements to test? ✅ Since repos take the templates from main, testing requires a fork.
• Any UI changes? Include screenshots if so. ❌

Feelings gif (optional)

Please make sure you've attempted to meet the following coding standards

• Code has been tested and does not produce errors
• Code is readable and formatted
• There isn't any unnecessary commented-out code
