temp: point xblocks-contrib to PR #262 branch for CI testing

Replaces the xblocks-contrib==0.17.0 PyPI pin with a direct git
reference to the modernize-problem-block-js-438 branch on the fork,
so the ES6+ Problem Block JS changes can be tested end-to-end in
a running platform instance.

PR under review: openedx/xblocks-core#262

Do not merge — this branch will be deleted once the xblocks-core
PR is merged and a new xblocks-contrib release is published.
