prism-redux/escapeRegexp.js is missing a character in the regex

[jcheroske]

The replace() call is missing a '$' character:

Original file:

const ESCAPE_PATTERN = /[|\\{}()[\]^$+*?.]/g;

export default (value : string) => value
  .replace(ESCAPE_PATTERN, '\\&');

Should be

const ESCAPE_PATTERN = /[|\\{}()[\]^$+*?.]/g;

export default (value : string) => value
  .replace(ESCAPE_PATTERN, '\\$&'); // <-- need a $ here!
