partition_html is returning javascript code from some HTML documents

[MthwRobinson]

Currently, the partition_html function is returning javascript code in some html documents. The goal of this issue is to update our partitioning logic so that this javascript code doesn't come through in the example document.

Steps to reproduce

import requests
from unstructured.partition.html import partition_html

url = "https://www.understandingwar.org/backgrounder/russian-offensive-campaign-assessment-december-13"
r = requests.get(url)
elements = partition_html(text=r.text)
 print("\n\n".join([str(el) for el in elements[:5]]))

You should see the following javascript code in elements[1].text

'(function(d){\n  var js, id = \'facebook-jssdk\'; if (d.getElementById(id)) {return;}\n  js = d.createElement(\'script\'); js.id = id; js.async = true;\n  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";\n  d.getElementsByTagName(\'head\')[0].appendChild(js);\n}(document));'

For the document in question, it looks like the offending javascript is actually coming back in a <td> tag. is_possible_narrative_text is also flagging this block as narrative, which isn't right. I think we actually are already the script tags.

'(function(d){\n  var js, id = \'facebook-jssdk\'; if (d.getElementById(id)) {return;}\n  js = d.createElement(\'script\'); js.id = id; js.async = true;\n  js.src = "//connect.facebook.net/en_US/all.js#xfbml=1";\n  d.getElementsByTagName(\'head\')[0].appendChild(js);\n}(document));'
