Fix and improve view-transition-class page

[TGianella]

Description

Corrects several issues related to custom-ident value description in view-transition-class doc (1 commit for each, in this order):

• It does not need to be unique
• It does not cause the element to participate in a separate view-transition group
• Several custom-ident are supported but apart from the formal syntax the first sentence of the doc implies that only one class can be given.

Motivation

I came to this article to know whether I could use several custom-idents on one element and I missed the + in the formal syntax but nowhere else in the doc this is said and I feel readers could benefit from a bit of redundancy and more clarity.

The value description field was plain wrong, the info is true for view-transition-name but not for view-transition-class so it contributes to keep the confusion going between these two.

Good catch! Thank you 🙂

I would go the extra step and make sure it’s clear, both from the description and additional examples. What do you think?
