Phlex deprecation warning

[mathias234]

Hello, after adding this gem we are receiving a deprecation warning from phlex

⚠️ [DEPRECATION] Defining the `template` method on a Phlex component will not be supported in Phlex 2.0. Please rename the method to `view_template` instead.

We do not use Phlex ourselves in the project.

Same, I think I somewhat disagree with this project's decision to include phlex when a lot of projects won't be using it... it's just another dependency that's not used for anything but this gem, heh.
