Declarative Shadow DOM in Chrome 90-110 needs a note

[foolip]

Note in https://developer.chrome.com/docs/css-ui/declarative-shadow-dom:

Declarative Shadow DOM has been available since Chrome 90 and Edge 91, but it used an older non-standard attribute called shadowroot instead of the standardized shadowrootmode attribute.

It would be good if this was reflected in https://caniuse.com/declarative-shadow-dom with a note for Chrome 90-110. I'm not sure about Edge 90, but assume that comment is right and it was shipped in Edge 91.
