Add support for new issue experience in all repos

[guywillis]

Subject of the issue

GitHub have publicly enabled the 'new issues experience' preview feature. This preview feature is not compatible with the current implementation of the issue template.

The 'new issues experience' feature appears to be toggleable on an account basis rather than at an organisation level.

As such, to ensure all audiences are covered, it is proposed to retain the existing implementation and add in support for the 'new issues experience' feature.

Steps to reproduce

When selecting 'New issue' on a repo, the issue title and body fields are blank.

Navigating to the .github/ISSUE_TEMPLATE.md file you're met with the following error message:

Proposed fix

• Copy the current ISSUE_TEMPLATE.md from .github/ and paste it .github/ISSUE_TEMPLATE/
• Add YAML frontmatter to .github/ISSUE_TEMPLATE/issue_template.md
• Add config.yml file to .github/ISSUE_TEMPLATE/
• Update config.yml to remove the blank issue option when creating an issue

Example of YAML frontmatter:

---
name: Issue
about: Use this template for reporting issues
title: ""
labels: ""
assignees: ""
---
