update about-how-to.md

[shreyas1599]

• Changed file name as per kebab case vs camel case vs  #55
• Implemented changes suggested in lead paragraph about-howto #85

This is the job of a How-to article.

Seems unnecessary
I also suggest rewording:

How-to articles are often confused with tutorials, but you won't fall into this trap if you remember they are problem-oriented not learning-oriented.

To something like:

How-to articles are often confused with tutorials, which is not the case as they are problem-oriented not learning-oriented.

Will add a commit after review by a maintainer.

@shreyas1599 Yep I agree with your rewording of the explanation about how-to articles. Go ahead with your proposed fix to that paragraph.

@jaredmorgs Done!

@jaredmorgs can you close #55 and #85?
