Fix another Less syntax error in core v4.17.3 variables.less:

@pt-dark-input-intent-box-shadow-colors: {
  primary: #4c90f0;
  success: #32a467;
  warning: #ec9a3c;
  "danger":#e76a6e, ;
};

should be instead (fixed):

@pt-dark-input-intent-box-shadow-colors: {
  primary: #4c90f0;
  success: #32a467;
  warning: #ec9a3c;
  danger: #e76a6e;
};

Regression test
