Update phoenix_html to 4.0.0

[adamu]

phoenix_html has been updated to v4 with breaking changes: https://hexdocs.pm/phoenix_html/changelog.html#v4-0-0-2023-12-19

I took a look at doing the migration myself, but I'm guessing this library will want to do more than the minimal changes to update and keep the code compiling, it'll probably want to avoid the dependency on the new (legacy) phoenix_html_helpers library, so I'm just opening the issue for now.

Thanks for this @adamu

@cpjolicoeur Is there any progress on this? If you like I can work on a PR that introduces the phoenix_html_helpers library, which would stop Torch being a blocker for people updating to phoenix_html v4.

I think this can be closed now following #452 and the latest release (but heads up that the Hex docs appear to be broken).

Thanks @adamu I'm not sure what is up with the docs but I'll look into it and republish them

@adamu docs have been fixed and re-published. Thanks for noticing that.
