Update README, fixed badly-styled eslint links 
Update README, fixed badly-styled eslint links 

There were links to eslint rules in a style that didn't match the style of the rest of the document. Specifically, most links in the document use the following style: "eslint: ['no-unneeded-ternary']", but there were badly styled links that looks like this: "eslint rule: ['no-unneeded-ternary']." Additionally, the badly styled links were on their own line, whereas all the other links are not placed on their own line.
