fix: remove unsupported path property from default document view configs (#12774)

Customizing the `path` property on default document views is currently
not supported, but the types suggest that it is. You can only provide a
path to custom views. This PR ensures that `path` cannot be set on
default views as expected.

For example:

```ts
import type { CollectionConfig } from 'payload'

export const MyCollectionConfig: CollectionConfig = {
  // ...
  admin: {
    components: {
      views: {
        edit: {
          default: {
            path: '/' // THIS IS NOT ALLOWED!
          },
          myCustomView: {
            path: '/edit', // THIS IS ALLOWED!
            Component: '/collections/CustomViews3/MyEditView.js#MyEditView',
          },
        },
      },
    },
  },
}
```

For background context, this was deeply explored in #12701. This is not
planned, however, due to [performance and maintainability
concerns](https://github.com/payloadcms/payload/pull/12701#issuecomment-2963926925),
plus [there are alternatives to achieve
this](https://github.com/payloadcms/payload/pull/12772).

This PR also fixes and improves various jsdocs, and fixes a typo found
in the docs.
