docs: Add org to the blogpost

[tgodzik]

Noticed, that Seth was actually adding the company, so I should probably add it too (also since we actually take care of LTS)

You or I might have also included "Scala core team" or some such, either in addition, or as a replacement.

I'd go along with consensus on this, if one develops. Including our employers is both a gesture of transparency to the community and a gesture of credit and thanks to our employers. But information about our role in the org is probably of equal interest to readers (possibly greater interest?).

But anyway, tiny issue.

for my own most recent blog post, I directly pushed ed67680 with a slightly different credit format; "Akka & Scala Core team" looked funny
