Import Prettier from prettier/standalone (#1024)

The import from `prettier` includes support for all languages supported
by Prettier. The `prettier/standalone` import only includes the core.
The `prettier` export also points to `prettier/standalone` for the
`browser` export condition.

This means that with this change `yaml-language-server` has to load less
code, leading to faster startup time. And depending on configuration, it
may lead to smaller bundle sizes.
