Map metadata from issue templates to NewIssue.md

[lache-melvin]

I have issue templates with metadata, e.g.:

---
name: Bug report
about: Report a bug, help us improve
title: A clear title describing the bug from a user's perspective
labels: bug, needs triage
assignees: username
---

[...some body...]

When I create a new issue using this template, the title is brought through, but the rest of the metadata is not included.

I.e. this is the generated NewIssue.md:

A brief title describing the bug from a user's perspective

Assignees: 
Labels: 
Milestone: 
Projects:

[...some body...]

Would be great to populate the metadata fields based on the issue template!

Just to be clear, I think you're suggesting the following (I've added some properties for completeness and made some modifictions for refinement):

---
issue-markdown-template: ./issue-template.md
body: Report a bug, help us improve
title: A clear title describing the bug from a user's perspective
labels: bug, needs triage
milestone: next
projects: project one
assignees: username
---

[...some body...]

would map to:

${{ title }}

Assignees: ${{ assignees }}
Labels: ${{ labels }}
Milestone: ${{ milestone }}
Projects: ${{ projects }}

${{ body }}

With this modification, the GitHub Issues VS Code extension would use the YAML to populate the issue template ./issue-template.md. A use case would be to provide one or more templates in a directory within the repository. With your YAML file open, the VS Code Command Palette option might read "GitHub Issues: Create issue from YAML" or "GitHub Issues: Create issue from YAML using template". In either case, a preview of the generated issue would open and the user could create the issue from the preview.

Expanding this issue further, it could be possible to create issues in bulk with multiple blocks provided within the same YAML file. Perhaps the YAML could be automatically updated following issue creation with the issue number. This could be advantageous when tracking multiple related issues.

Yes exactly! Thank you 🙏
