Subject: [PATCH] python3Packages.dfdiskcache: relax pandas<3 upper bound

nixpkgs bumped pandas to 3.0.4, which trips df-diskcache's pinned
'pandas<3,>=1' runtime dependency check. Upstream still pins pandas<3
as of the v0.1.0 tag (no indication of pandas 3 testing), but the
package's own test suite (4/4) passes fine against pandas 3.0.4 here.

This was breaking the sbomnix build, which depends on dfdiskcache.
