python3-idna: set CVE_PRODUCT

The pypi class default python:idna matches nothing in the CVE
databases, which track the Python idna CVEs as:

* CVE-2024-3651 (kjd:internationalized_domain_names_in_applications) [1]
* CVE-2026-45409 (kjd:idna in the CNA record, same NVD CPE as above)

Set both vendor:product pairs.

For scarthgap, python3-idna is 3.7. CVE-2026-45409 affects idna
versions before 3.15, so this metadata change will expose that CVE as
applicable/unpatched. The fix for CVE-2026-45409 needs to be handled
separately.

The bare product name is not an option here: it would also match
"servo:idna", the Rust idna crate (e.g. CVE-2024-12224).

Note: Original commit was for python3-idna_3.11.bb. This is adjusted
for scarthgap where recipe version is python3-idna_3.7.bb.
