Refactor updateDownloadLink function

[melvincarvalho]

Current implementation:

updateDownloadLink() {
  const inputSlug = document.getElementById("file-name").value;
  const downloadLink = document.getElementById("download");

  let filename;

  filename = inputSlug;

  const path = getPath(serverUrl, userPublicKey, filename, mode);
  downloadLink.setAttribute("href", path);
}

Suggested improvement:

updateDownloadLink() {
  const filename = document.getElementById("file-name").value;
  const downloadLink = document.getElementById("download");
  const path = getPath(serverUrl, userPublicKey, filename, mode);
  downloadLink.setAttribute("href", path);
}

The suggested refactor removes unnecessary variable assignments, making the function more concise and easier to read.
