[PATCH 2/7] python3: inherit upstream-stable-release-point

[<daniel.turull@ericsson.com>]

From: Daniel Turull <daniel.turull@ericsson.com>

Python maintains each release series on a per-minor maintenance branch
that, once released, takes bug and security fixes only, and it releases
from several at once: 3.10.20, 3.11.15 and 3.12.13 all went out on
2026-03-03, after 3.14.3. So upgrades within a major.minor are stable
point upgrades per the OE-Core stable release policy (ref-manual, "Stable
Point Release Upgrades").

  https://docs.yoctoproject.org/dev/ref-manual/release-process.html#stable-point-release-upgrades
  https://devguide.python.org/versions/

Checked the last three point releases by category, since these are
substantial bug-fix releases rather than security-only. 3.14.6 (Jun 10
2026) has 8 Security, 32 Library and 17 Core entries; 3.14.4 (Apr 07 2026)
has 5, 59 and 46. Every C API entry in both is a fix, so neither adds C
API. 3.14.5 (May 10 2026) is mostly fixes but does add RFC 9309 support to
urllib.robotparser -- one extra capability in one module, touching neither
the language, the C API nor the stable ABI.

Already tracked this way on the OE stable branches, counting only bumps
since each branch forked: kirkstone 3.10.4 -> 3.10.20, scarthgap 3.12.3 ->
3.12.13, wrynose 3.14.4 -> 3.14.6.
