fix: update build and distribution configuration

[jboix]

Description

Addresses several updates to the distribution configuration.

Changes made

• Removed browser field to prioritize module imports.
• Added style and types field to the package.json.
• Updated the output file name in the "build:css" script from video-js.min.css to pillarbox.min.css.
• Updated the quick guide to reflect how to properly integrate the library.

---

These configuration was tested in conjunction with the demo (see SRGSSR/pillarbox-web-demo#7) to ensure that the library is easily integrated as a npm module.
