docs: add two extensions

[barakplasma]

Might also want to add a link to the github topics I found these two extensions from: https://github.com/topics/directus

I also want to add my template repo for deploying Directus to Render https://github.com/barakplasma/directus-on-render but I don't know which section it would go in.

Thanks! Feel free to create a new section called "Templates" (maybe below "Tools") 👍 Your template repo seems to be pretty specific to your use-case, I'm afraid we can't add it to this list in this form.
