Editorial: "Web" to "web", "Success criteria" to "success criteria"

[patrickhlauke]

Also includes:

• change "web based" to "web-based"
• change "Web Unit" to "web unit"
• change "Web Page" to "web page" (where appropriate)
• a few straggler cases where lowercase "success criterion/criteria" was referring to specific ones, where we do want title case

Closes #4427

We should skip the HTML files under conformance-challenges and requirements

I learned that terms like "section" and "success criterion" are supposed to be written starting with a capital letter if a number follows, like "Section 4" or "Success Criterion 1.4.11".
Is that not true? (or has changed over the past decades?)

and are any of the changes here contradicting that?

actually, though i wasn't specifically looking for that case, it seems there's some cases in the current wording of certain files where it's right now lowercase when it shouldn't be, so will actually tackle that now here too
