refactor: add github actions and format styles for prettier configurations

[vexra]

In this pull request I added github actions, dependabots and changed the configuration for prettier. I also changed the use of the package manager which originally used npm to use pnpm.

In the dependabot.yml configuration, it is used to always update the package to the latest version every month so that the project will receive notifications to always update the package to maintain security.

In the build github action will run the pnpm run build command to check if the project is successful. While the dev github action will run pnpm run prettier this is done to check the format of the code that must match the configuration. And pnpm run lint to check for type errors.

I also changed the use of the package manager which originally used npm to use pnpm because pnpm is safer, faster, lighter, and saves on storage usage for node_modules.
