Update gem dependencies

[sylhare]

Use latest Jekyll-feed: https://github.com/jekyll/jekyll-feed Use latest Jekyll-Seo-tag: https://github.com/jekyll/jekyll-seo-tag/blob/master/docs/usage.md

I need it to be compatible with GitHub page https://github.com/github/pages-gem

@sylhare have you thought of any new features for Type on Strap?

[sylhare]

Yeah I have been adding / updating stuff. If there's a particular feature you are interested in having here let me know

Netlify CMS support?

[sylhare]

You can open an issue with it, but I doubt there's anything to do on the theme side, it's more of Netlifty being compatible with Jekyll.
