Feature: Automate Extension Publishing with GitHub Action

[taj54]

Hi there 👋,

I noticed your repository publishes a VS Code extension. I wanted to share a useful GitHub Action that could help streamline your release workflow.

The action is HaaLeo/publish-vscode-extension and it allows you to automatically publish extensions to:

• Open VSX Registry (used by VSCodium, Gitpod, etc.)
• Visual Studio Marketplace

With this action, you can:

• Package your extension once and publish it to multiple registries.
• Use secrets to securely store tokens.
• Skip duplicates and even run dry tests before publishing.
• Automate release on tag push, PR merge, or manual trigger.

Example Workflow

on:
  push:
    tags:
      - "*"

jobs:
  release:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v4
      - uses: actions/setup-node@v4
        with:
          node-version: 20
      - run: npm ci
      - name: Publish to Open VSX
        uses: HaaLeo/publish-vscode-extension@v2
        with:
          pat: ${{ secrets.OPEN_VSX_TOKEN }}
      - name: Publish to VS Marketplace
        uses: HaaLeo/publish-vscode-extension@v2
        with:
          pat: ${{ secrets.VS_MARKETPLACE_TOKEN }}
          registryUrl: https://marketplace.visualstudio.com

🙋 If you’d like, I can open a PR to add this workflow.
