ci: created github actions workflow for automatically formatting, linting, and type checking

[Neil-urk12]

Automation feature

• this script automatically runs pnpm format, pnpm lint, and pnpm check to detect issues in commits and pull requests
• this change ensures code quality automatically and detect issues on future contributions and changes

Steps to apply this github actions workflow in repository

1. Navigate to repository settings, then go to Secrets and variables
2. Go to Actions then create a 'Repository secret' and name it GOOGLE_GENERATIVE_AI_API_KEY and just add any random value.

The value won't matter since the script "svelte-kit sync && svelte-check --tsconfig ./tsconfig.json" just needs the variable to exist. It doesn't connect or use the value at all, just type checking.

Note: GOOGLE_GENERATIVE_AI_API_KEY is required in the repository secret. Random values are okay
