chore(docz-components): change item key and filename comparison

[Kerumen]

Description

When we try to write a Docz for a package located elsewhere (in a monorepo for example), we face the "props-problem".

In doczrc.js, if we set docgenConfig.searchPath to the relative root of our components, in the stateProps every item key is relative:

{ key: '../../packages/components/src/Button/index.tsx', value: [] }

However, the __filemeta.filename will always be the dist/index.js file. To avoid that, I build my library with babel-plugin-export-metadata (cf #1173). The __filemeta.filename key is now resolved to:

{ filename: 'src/Button/index.tsx' }

With the comparison item.key === filename, it still doesn't match. I changed it to includes because it's more permissive. Also, it's not a regression because if item.key === filename it will still match.

Hello @rakannimer

Thanks for the merge. I upgraded to v2.0.0-rc.58 and it was not included in compiled file. Something was missing during the publish step?
