Make OnceUI a NPM package that can ge integrated from non-template project.

[SnowDingo]

Describe the feature To use OnceUI in a project, there are currently two methods;

1. Use magic-portfolio
2. Use a next-starter project.

Adding once-ui as one of the npm or yarn package systems is beneficial, especially for people who want to update their once-ui system or integrate it into an existing project.

Other UI design systems like MUI, Antd design, and Bootstrap all have some ways to add to existing projects and update them without the need to clone a new project and follow the migration process.
