This commit adds a new GitHub Actions workflow file, artifacts.yml, which is triggered on push events to the main branch. The workflow consists of two jobs: "filter" and "build".
The "filter" job checks if any of the specified files (package.json and assets/**) have changed. If any file in the scope has changed, a step is executed. Otherwise, the workflow is prevented from running.
The "build" job is executed if the branch is main and the repository is not a fork. It performs the following steps:
1. Checkout the repository
2. Setup pnpm package manager
3. Get the pnpm store directory path
4. Setup pnpm cache using actions/cache
5. Install dependencies using pnpm
6. Build the artifacts
7. Configure git user email and name
8. Add all changes to the commit and commit with the message "build: update bundled artifacts [skip ci]"
9. Push the changes to the repository
