Improve documentation

[camilogarciabotero]

Cool 🎉 🎉 🎉 ! Thanks for following this #129

I have a couple of thoughts for the docs, I am willing to improve:

• Bring a new tab section called Articles (and let this for more thorough analyses)
• Add TidierDB with the new logo.
• Add another document in the Get Started section to include a short use case for TidierPlots.jl
• Add some comparisons to R using code tabs a la PairPlots.jl (suggested here)
• Add missing links for package documentation in the home
• Add TidierDB short get started.
• Include more links to other Julia packages (?)

Any other ideas to make this a meta issue?
