Upgrade deps, add storybook

[dev-shah7]

Changes

Adds phoenix storybook dependency along with example pages for dropdowns and basic inputs. In order to make it work I had to upgrade some deps:

• phoenix_ecto to 4.5
• phoenix_html to 4.1
• phoenix_live_view to 1.0

There were some breaking changes which I'll take notes on in self-review

There are a couple known issues with storybook installation:

1. The storybook area (./storybook) uses its own JS bundle which is using pre-1.0 version of liveview. This causes a console warning but no real-world issues as far as I can tell. A new version of storybook should be released this week with support for Liveview 1.0
2. For some reason, when you navigate to a page with Alpine.JS component (Input -> Dropdown) it causes some error from AlpineJS. When you load the page with AlpineJS directly it works fine. I wasn't able to find a fix.
