Sage needs to upgrade the pip, uv and certifi spkgs

[Marc Culler]

I see that the certifi spkg is at 2026.2.25.  That version includes the eMudhra emSign certificate which allows accepting a private key with less than 8 bits.

See https://discuss.python.org/t/information-for-python-users-regarding-emudhra-emsign-ca-certificate-security-incident/109576

This has caused python.org to generate security releases of 3.13, 3.14, and 3.15:

Thanks. We'll upgrade pip along with it, as it bundles its own certifi.
