Replace Graphemer by Intl.Segmenter()

[tiagofilipenunes]

Graphemer is used in the app to perform non-trivial split of strings, for strings such as >1-char emojis used in ENS addresses.

Intl.Segmenter is now widely supported since Firefox 125 (16th April) has included it. Graphemer can be easily replaced by Intl.Segmenter.

Before:

  const splitter = new Graphemer();
  const stringArray = splitter.splitGraphemes(stringToShorten);

After:

  const segmenter = new Intl.Segmenter();

  const stringArray = [...segmenter.segment(stringToShorten)].map(
    (segmentData) => segmentData.segment
  );
