Evaluate and add linting to detect at pull request issues in the change #45

When contributor submits a pull request, we should automatically detect using linting potential issues with the change. The potential issues could be:

1. Linking to an image with incorrect path
2. Missing link, perhaps they forgot to specify the target hyperlink
3. When page is missing a mention of sidebar id
4. Has code but has not surrounded the code with back ticks. For example: /learn/request-response-processing-rest-services.md
5. Has HTML code that is not fenced properly leading it to be executed by browser causing nasty issues like Popup shown in OWASP page #97
