Events: Add from and to scene names to transition events

[duncte123]

Description

As stated in #983 the v5 transition events are lacking a severe amount of data rendering them pretty much useless without having your own state (that desyncs the moment you have two clients)

Motivation and Context

The missing from and to scenes on the transition events is what's keeping me on v4. When this PR is released I will be able to switch off v4 and use v5.
It would fix #983 but currently the duration is missing so it's not fixed completely.

Whoops, soft resetted too much

I'd be thrilled to have this merged, knowing what scene is being transitioned to as the scene transition starts is very useful for me.

@duncte123 - Should the transition events also contain the UUIDs of the scenes being transitioned from and to?

Personally I don't have any use case for this, if any of the maintainers want this functionality I'd be happy to add it next to the scene names
