[dependabot-preview]

Updates the requirements on oga to permit the latest version.

Changelog

Sourced from oga's changelog.

3.1 - 2020-01-08

This release fixes a bug in the XML lexer that prevented the parsing of doctypes using "public" or "system" instead of "PUBLIC"/"SYSTEM". See issue https://gitlab.com/yorickpeterse/oga/issues/199 for more information.

3.0 - 2019-12-03

This release bumps the Ruby version requirement to Ruby 2.3.0, as we haven't supported older versions for several years now. We also no longer officially support Rubinius.

2.17 - 2019-12-02

Elements using the default XML namespace can now be queried using XPath queries, which was broken for quite a while.
