Liveview (0.19) & deps updated

[nathanmalishev]

Updated mix to use Liveview 0.19 and updated other decencies as well.

Modified the test that checks the 'Global attribute' docs as it must have changed as well. (test/heroicons_test.exs:96).

Concerning the failing "generating docs" test: since phoenix_live_view 0.18.4 the function build_attrs_docs is changed. In case of a global attribute you can't declare documentation for the attribute anymore, it just returns "* Global attributes are accepted.\n".

It seems inconsistent, because in the phoenix_live_view library itself in case of a global attribute document information is still provided

You can see this in the documentation of Phoenix LiveView as well. Note the difference in the documentation of the attributes of for example form/1

https://hexdocs.pm/phoenix_live_view/0.18.3/Phoenix.Component.html#form/1

and

https://hexdocs.pm/phoenix_live_view/0.18.4/Phoenix.Component.html#form/1
