Update workflow files.

[ColtMcG1]

This pull request updates the CI/CD workflows and package metadata to improve automation and consistency for publishing and releasing the VS Code extension. The main changes include adding a new workflow for publishing from the development branch, updating the release workflow to use Node.js 20 and caching dependencies, and standardizing the publisher name in package.json.

Workflow automation and improvements:

• Added a new workflow file .github/workflows/dev.yml to automate packaging the VS Code extension on pushes to the development branch.
• Updated .github/workflows/release.yml (renamed from .github/.workflows/release.yml) to remove tag-based triggers, so releases are now only triggered on pushes to the master branch.

Build and dependency management:

• Changed Node.js version from 18 to 20 and added a step to cache node_modules in the release workflow for faster builds.
• Updated the packaging command to use npx @vscode/vsce package for both workflows, ensuring consistency in extension packaging. [1] [2]

Metadata standardization:

• Standardized the publisher name in package.json from "Colton McGraw" to "coltonmcgraw" for consistency with marketplace requirements.
