fix: escape bs4 parsing error

[cachho]

I have previously spoken up against escaping errors. But this is different with bulk jobs like the sitemap. You don't want the whole sitemap to stop processing because one site failed.

This error escapes beautiful soup's ParserRejectedMarkup error. I found this happens when a file attachment page made it to the sitemap, that's just the attachment and not an html file.

Example output:

2023-07-15 00:50:30,466 [root] [ERROR] Failed to parse https://example.com/verify.png: The markup you provided was rejected by the parser. Trying a different parser or a different encoding may help.

Original exception(s) from parser:
 unknown status keyword 'h' in marked section
