fix(SourcesCard): Fix jagged wrap layout

[rebeccaalpert]

Body text of differing lengths could lead to a jagged wrapped layout. Cards should now flex to maintain similar heights/widths.

Fixes #839.

Before	After

Can test with this example pasted into https://chatbot-pr-chatbot-854.surge.sh/extensions/chatbot/messages/#messages-with-sources.

import { FunctionComponent, MouseEvent as ReactMouseEvent, KeyboardEvent as ReactKeyboardEvent } from 'react';
import Message from '@patternfly/chatbot/dist/dynamic/Message';
import patternflyAvatar from './patternfly_avatar.jpg';
import { Button, Flex, FlexItem, Label, Popover } from '@patternfly/react-core';
import { OutlinedQuestionCircleIcon } from '@patternfly/react-icons';

export const MessageWithSourcesExample: FunctionComponent = () => {
  const onSetPage = (_event: ReactMouseEvent | ReactKeyboardEvent | MouseEvent, newPage: number) => {
    // eslint-disable-next-line no-console
    console.log(`Page changed to ${newPage}`);
  };

  const date = new Date();

  const datePart = date.toLocaleDateString('en', {
    year: 'numeric',
    month: 'short',
    day: 'numeric'
  });

  const timePart = date.toLocaleTimeString('en', {
    hour: '2-digit',
    minute: '2-digit',
    hour12: true
  });

  const formattedDate = `${datePart}, ${timePart}`;
