readme edits to C/T/R

Addresses: #73
Additionally, frames the C/T/R discussion in terms of the information seeking behaviour (learning/doing/fact-checking).
Also, removed some of the word/phrases that my current linters didn't like.

Question for maintainers: I noticed the use of en_GB spelling in this doc, and couldn't find guidance on dialect. Is there a preference?

Excellent revisions, Lana. I like the parallelism in the revised sections.

I believe we have shifted to en_US in line with the Google Developer Style Guide.

Thanks for the review, Jared. Are you able to add more reviewers to the list? I don't have perms.

I have perms now, so have added the suggested reviewers.

Given the approval from Jared and thumbs up from me and Loquacity, I'm merging this PR.
