Audit deprecated eslint rules

[zepumph]

While working on #1429, I found that the JSON output provides a list eslint rules that we use that are deprecated. Perhaps we should discuss if these should be updated or changed.

Here is the list of deprecated rules I got from running the below script in chipper. This also may be a helpful link: https://eslint.org/docs/latest/rules/#deprecated

 const deprecatedRules = [];
    results.forEach( result => {
      deprecatedRules.push( ...result.usedDeprecatedRules.map( x => {
        return x.replacedBy.length > 0 ?
               `${x.ruleId}->${x.replacedBy.join( ',' )}` :
               x.ruleId;
      } ) );
    } );
    console.log( _.uniq( deprecatedRules ).join( '\n' ) );
