add turbo stream morph actions to broadcasts

[omarluq]

This PR adds support for the Turbo Stream Morph action Turbo::StreamsChannel.broadcast_morph_to and it's variants, complementing the Morph action PR hotwired/turbo#1185

This looks great @omarluq. One minor comment. Thanks!

Thanks @omarluq!

@jorgemanrubia when could we expect to get this in a release?

[paulsturgess]

I just got tripped up trying to use this, as I thought the morph action was available.

Is there a plan to get this released? Thanks!

[searls]

Yeah @paulsturgess, just tripped over this myself.

Looks like the docs PR was reverted, and @jorgemanrubia refers to a different API that is described in this open PR, so I assume this was undone and nobody left a link in the original issue or this PR.

Would love if someone could let us know what the plan is!

@searls @paulsturgess Sorry about the confusion here! I reverted the documentation change for this one since we hadn't done a release containing it, so people were confused when they saw it in the docs, but it didn't work. Also, @seanpdoyle reworked the API to support this here hotwired/turbo#1240.

What we will do this week is to release a new version of turbo and turbo-rails containing the latter version of this (#1240), and then we'll merge the docs changes.

Sorry about the confusion 🙏 .

Thanks for this! Excited to remove my home-rolled implementation and shed the direct idiomorph dependency.
