Announce the launch of Skolar for the scikit-learn community

[pengtts]

The Training & Certification Team at Probabl has recently launched Skolar: an open-source initiative to democratize open data science education, especially free training on machine learning with scikit-learn - this PR suggests its launch announcement.

Thanks @pengtts, just a couple of suggestions.

Hi @pengtts @ArturoAmorQ
I'm reviewing the post and have the following comments / questions:
a) the file name needs to follow this format: yyyy-mm-dd.....
b) skolar is fully open source? Can a link to the GitHub repo be added somewhere? Is it the same as skore?
c) wonder if there should be a line at the top indicating this is a sponsor post, and not a scikit-learn project post, for clarification.

[ArturoAmorQ]

As per RL communication with @pengtts, I took the liberty to push some changes to this PR. I hope they help address your comments @reshamas :)

Thanks for the clarification in the authorship of this blog post and making the relationship between the probabl company and the scikit-learn project explicit. LGTM on my end, but I would like @reshamas or other non-probabl project members to give a +1 prior to merging/publishing.

Is this the right image to use? It sounds like it is some default thing?

A few wording suggestions. Mostly about who is who/who is the voice of the post

A few suggestions, even if they say something slightly different to my interpretation of the original

(I don't know if posting three suggestions will work or not, maybe don't use the GitHub UI to apply it?)

"... With their support ... , we continue"

Maybe we can make it more explicit who is who here. At least I'm a bit lost if for example the "their" is the group of engineers employed by probabl, or probal or someone else? If it is probabl I think "With probabl's support and ..." would be clearer

Again I think it is a bit unclear whose community it is if we use "our". Given the post is written by probabl the most straightforward interpretation is that "our community" is "probabl's community" which doesn't seem quite right. I like "the community", avoids any suggestion that it belongs to anyone

Should we link to the homepages of these libraries?
