New vendor/product profile information. And a small typo fix for the main listing page.

I'm reviewing the validation issues.

Thank you! Besides that, if you could provide more source_url references for the partial/full support claims, that would be also very helpful for the reviewers and community broadly - folks love to dive into docs/examples when exploring how you support each given feature.

Thanks @svonava - also, could Erlang be added to the dev langs schema for validate options?

Added, make sure to lowercase all the options / see how the other files do this.

Thanks for the feedback! Addressed most issues, awaiting on a few docs links for a couple newer features, but otherwise ready. Will keep up to date when I get more links to add.
