docs: Create symbolic link
  @function $file~link
  @param {string} target - Target of the link
  @param {string} location - Location of the link
  @param {Object} [options]
  @param {boolean} [options.force=false] - Force creation of the link even if it already exists
  @example
  // Create a symbolic link 'libsample.so' pointing to '/usr/lib/libsample.so.1'
  $file.link('/usr/lib/libsample.so.1', 'libsample.so');
