Consider setting up auto-publishing

[jackyef]

Since Iconic is planning to add new icons every week, we could consider adding a script that can handle fetching new icons, generate the components for them and publishing to npm just create a PR to the main branch.

Due to the way we are fetching new icons (scraping the iconic.app HTML), it might not be safe to auto-publish as we have to make sure nothing breaks beforehand.

The commit message could be as simple as chore: Add {number} new icons (v1.0.x)
