Feature request: Add issue templates for tasks and a11y issues

[mejiaj]

Summary

Add issue templates to create task and a11y type issues quickly with the correct metadata.

Describe the solution you'd like

• Task type template for basic chore-like/maintainability work.
• A11y template to capture the issue and severity

Most importantly, these would have the correct metadata for label and issue type automatically.

Alternatives you've considered

Continuing with existing templates, but won't always produce consistent issues.

Additional context

I've added an a11y template in our HUD project.
