[WIP] Update jsoup version

[whyoleg]

Jsoup changelog.

By simply updating the version, several things were broken:

1. escaping of ' and "
   • Fixed in the PR: at some version, jsoup supported escaping for attributes, which is stricter, and so Entities.escape started to escape characters, which we don't need to be escaped.
2. inheritDoc injection
   • TBD: tests are failing.
3. accessors in javadoc format are missing
   • TBD: if it's a generator or an issue in tests)
