Add publish ci

[xpirad]

This pull request introduces a new GitHub Actions workflow for publishing the package, updates the package's metadata for scoped publishing, and adds a new npm script for running all checks in parallel (the script also applies prettier fix automatically). Below is a summary of notable changes:

Workflow Automation

• Added a new GitHub Actions workflow in .github/workflows/publish.yml to automate the publishing process. The workflow triggers on any push to a tag, and does the following things: installs dependencies, builds the project, and publishes it to npm using authentication token.

Package Metadata Updates

• Updated the name field in package.json to use a scoped package name (@schleifner/assemblyscript-eslint-plugin).
• Added a publishConfig field in package.json to specify the npm registry URL for publishing.

Script Enhancements

• Added a new npm script run-all in package.json to run linting, testing, spell-checking, and formatting in parallel. This all-in-one script helps facilitate the testing process.
• Added the npm-run-all package as a development dependency to support the new run-all script.
