Update the error message for update_page function

[aujjwal-smarsh]

Hi all,

I have been using the API for a long time. Thanks to all the contributors for the great work. It has helped me a lot for automating content pushing and updating.

I was facing this error continuously:

No space or no content type, or setup a wrong version type set to content, or status param is not draft and status content is current

I checked into the function and found it in the page https://github.com/atlassian-api/atlassian-python-api/blob/3ee13e384c2e7f642af9aae3066b22f09321e3b6/atlassian/confluence.py

But none of the things were coming out to be correct as I could see from the error message. Everything was fine in my code and it was working for a set of data while failing for the other set. I debugged a lot before finding that because of an & in my body (html body which I was trying to push) it was failing. I removed the & and it's working great.

 <tr>
                                <td style="border: 1px solid black;">
                                Company & Co. Inc.
                                </td>
                                <td style="border: 1px solid black">
                                0
                                </td>

If anyone can modify the error message to point out this situation as well it can prevent hours of debugging.

And for others finding there way here, you can use html.escape() to escape a string to HTML-safe: https://docs.python.org/3/library/html.html#html.escape

In my case, the html was already escaped but the issue was with a control character in the data.

Doing the below solved the problem

body = re.sub(r'[\x00-\x1f\x7f-\x9f]+', '', body)
