RecursiveUrlLoader class should return visted url too

[Shree7676]

Checked

• I searched existing ideas and did not find a similar one
• I added a very descriptive title
• I've clearly described the feature request and motivation for it

Feature request

RecursiveUrlLoader presently doesn't provide any endpoint through which we can get to know what all urls it has visited.
It already has the variable name in the class which keeps track of it. It would be better a method would help us access all the link that it has visited.

Motivation

Few Pages get missed and it would be easier to track that if we know what all pages we have visited

Proposal (If applicable)

Just a new method which returns the existing variable "visited_url". It is already keeping track of it but not sharing with user.
