feat: add storybook

[martinbianchi]

closes #131

@osdiab I succesfully implemented storybook and create some stories for the Widget and the Generic Button. I do not have access to Vercel but maybe would be a nice idea to use storybook as a preview for the widget

[osdiab]

nice! yeah that's a great idea, we can add that in a separate PR.

[osdiab]

great start!

[osdiab]

looks like the build got messed up somehow on this PR. debugging.

[osdiab]

seems to be because storybook uses html-webpack-plugin@4 but the preact app and our hacked together config uses html-webpack-plugin@3. fixing it. this is an argument for #75

[osdiab]

ugh looks like preact-cli only supports @3 and storybook only supports @4, which are mutually incompatible and causing issues when building. might need to move the storybook to a separate subpackage to make it work.

[osdiab]

i'm gonna hold off on merging this for now because of the build errors

[osdiab]

created issue on preact-cli here preactjs/preact-cli#1551

[martinbianchi]

@osdiab I checked on my local environment and everything was working fine until I updated the html-webpack-plugin version to the 4.5.2 as you said. So I downgraded the version to the 3.2.0 that it's the version that preact uses and both compilations are working, at least on my local env. Do you think that for the time being is a possible solution to this problem?

[osdiab]

oh sweet - nice! let's merge it then!
