all: Bump default container image to Fedora 39 (#1134)

Best-effort, search-and-replace. Checked manually using:

    % rg -iC1 'fedora.*38'

Fedora 39 was released 2023-11-07 (about 2 months ago)

imho, 2 months is enough of a grace period. Thoughts?

- Fixes #1119

 The `--init` flag is useful to create system containers, where the container acts
 more similar to a full VM than an application-container.
