Updated ESlint dependencies

[muhdhasan]

1. Updated the following dev dependencies below
   a. eslint 4.19.1 to 8.57.1
   b. eslint-config-standard 11.0.0 to 17.1.0
   c. eslint-plugin-import 2.13.0 to 2.32.0
   d. eslint-plugin-markdown 1.0.0-beta.6 to 5.1.0
   e. eslint-plugin-node 6.0.1 to 11.1.0
   f. eslint-plugin-promise 3.8.0 to 6.6.0
2. Removed deprecated eslint-plugin-standard because eslint-config-standard does not require it anymore from 16.0.0 and later.
3. Removed a blank line at the start of test.js after the updated dependencies above caught it.
4. However, when running npm run lint, warnings and errors will appear respectively mainly because of the no-var rule and parsing errors coming from markdowns. These were not present prior to updating the dependencies. Should be ok to merge this request.
