Rename the view transition meta tag ?

[Intrepidd]

The meta tag used to enable view transitions (view-transition with same-origin value) was chosen to mimic the one in the spec for MPA view transitions. See #935

However, it has now been removed in favor of a configuration directly in the css :https://developer.chrome.com/docs/web-platform/view-transitions/cross-document

With the meta gone, I'm wondering if we should rather not try to piggy back on the mechanism for MPA view transition and rather be explicit, maybe with a meta named turbo-view-transition ? Similar to the ones we already have for morphing / scroll / cache control.

I like that. Please do explore. Would need to maintain backwards compatibility, but we could recognize both names, and just use the new one going forward.

Fabulous, I opened #1380 that does just that, I just have some questions on testing strategy.
