fix: confluence anonymous access is failing after few requests

[baruchiro]

Fixes #144

The error is not always reproduced, and when it is, it is reproduced for a different page every time.

Since the error is 500, means that it is a server (Confluence) error, I can't fix it and I must work around it.

I added a retry mechanism and I enabled it only for our request, when it returns 500, it will retry it 3 times.

It looks like this:
