Fix react/no children prop eslint error

[BCerki]

I found this one tricky to understand, here are the docs I found in case they're helpful:

• eslint docs: https://github.com/yannickcr/eslint-plugin-react/blob/master/docs/rules/no-children-prop.md
• https://stackoverflow.com/questions/42982416/why-shouldnt-children-be-passed-as-a-prop

As far I can tell, this error arises because the Base Props interface has a prop named "children":

interface BaseProps {
  tag?: 'a' | 'div';
  dest?: Dest;
  symbol_?: Placement<LinkSymbol>;
  symbolClassName?: string;
  symbolStyle?: CSSProperties;
  iconSymbolSize?: number; //rem
  children?: ViewElementChildren;
  className?: string;
  style?: CSSProperties;
  disabled?: boolean;
  newTab?: boolean;
  focusable?: boolean;
  onClick?(e?: MouseEvent): void;
}

BaseProps is used all over the place, as is the word "children," so I think it would be time-consuming to fix this one. When I tried changing "children" in BaseProps to a different word, I got 400 lines of TS errors.
