support passing `--uploaded-prior-to` for recent pips

pip 26.0 added support for [--uploaded-prior-to](https://github.com/pypa/pip/pull/13625). This is useful for reproducible testing, as another way to work around partial uploads to registries, and as a supply chain attack mitigation . I'd like to be able to pass it through to `pip`. Naively I think this could be grouped with the other "Resolver Options".
