我想使用正则表达式来识别双引号内出现的逗号，然后我会想要删除那些逗号。引号中可以有任意数量的逗号，并且一行上可以有多组引号。所以这是一个输入和所需输出的例子：
dog, "apple, three", tree, cat, "orange, yellow", leaf =>
dog, "apple three", tree, cat, "orange yellow", leaf
dog, "apple, three, blue", tree, cat, "orange, jar, yellow", leaf =>
dog, "apple three blue", tree, cat, "orange jar yellow", leaf
我想删除引号中的逗号，而不是外部的逗号，并按原样保留其余的。
