fix(sdk): align Python Fedora/Alpine image defaults with JS (#1625)

Python `from_fedora_image` defaulted to `fedora:42` (end-of-life) and
`from_alpine_image` to `alpine:3.22`, while JS already pinned
`fedora:44`/`alpine:3.24` — the same call produced a different base
image per SDK. Aligns Python; also fixes the JS type docs, which still
named the old defaults.

```python
Template().from_fedora_image()  # fedora:44 (was fedora:42)
Template().from_alpine_image()  # alpine:3.24 (was alpine:3.22)
```

Follow-up to #1612; both defaults are still unreleased.

+Align the Python SDK's `from_fedora_image` and `from_alpine_image` defaults with the JS SDK: `fedora:44` and `alpine:3.24`, replacing `fedora:42` (end-of-life, so its repositories leave the normal mirror network and provisioning can fail) and `alpine:3.22`. Callers that omit the variant now get the same base image in both SDKs, and both tags are the ones the orchestrator's distro build tests cover. Also corrects the JS `TemplateFromImage` type docs, which still named the old defaults.
