build: replace build tool and automate builds

[parkerbxyz]

This pull request includes changes to the GitHub Actions workflows and the project's build process. The most significant changes include the addition of a new build.yml workflow, the removal of the setFailed import in index.js, and updates to the package.json file to change the build script and switch the build tool.

Build and Release Workflows:

• .github/workflows/build.yml: A new build workflow was added. This workflow triggers on pull requests and is responsible for setting up the environment, running the build script, and committing any changes to the dist/* files if the build is successful.

JavaScript Files:

• index.js: The setFailed import from @actions/core was removed because it was not being used.

Package.json:

• package.json: The build script was updated to use esbuild instead of ncc. [1] [2]
