undefined fuction `tap/1` in HomeScreen example

[aayushmau5]

Hello!
Taking out Mob for a spin. I stumbled upon an issue with the "Your first screen" example.

Here's the error:

Compiling 1 file (.ex)
    error: undefined function tap/1 (expected Eva.HomeScreen to define such a function or for it to be imported, but none are available)
    │
  9 │     ~MOB"""
    │     ^^^^^^^
    │
    └─ lib/eva/home_screen.ex:9: Eva.HomeScreen.render/1


== Compilation error in file lib/eva/home_screen.ex ==
** (CompileError) lib/eva/home_screen.ex: cannot compile module Eva.HomeScreen (errors have been logged

It seems the compiler is interpreting the sigil's tap string as a tap function.

Alternatively, this works:

<Button text="Save" on_tap={{self(), :increment}} />

Looking at the docs, we do follow this convention, so I think the example is out of date.
