Separate Exports

[awareness481]

• Check if Rollup fits the below requirements - Experimental exports #80
  1. Seperate export per file - Likely https://rollupjs.org/guide/en/#outputpreservemodulesroot
  2. CJS/ES6 exports (possibly esm as well)
• Provide a way to may contributing easy. Currently there's no conventional way of seeing your live changes for a component, except storybook which may be limiting. This should speed up development significantly.
• Setup a beta release channel. ex: npm i matte-ui@beta
• Verify the bundle size of each component
• Verify that the CSS of a component is loaded correctly in SSR

Additional points:

1. Start migrating leftover v4 code to v5 - Migrate Matte theme to MUI v5 #48
2. Add tests - Write tests #55
3. Setup GH actions for release - related: Setup CI/CD #54
4. Add https://github.com/semantic-release/semantic-release

This is too technical for me, so I am OK with what you decide. Please put each issue to the relevant milestone. Is it a basic need for v1? Put it in Version 1.0 milestone. Otherwise, put it to Next milestone
