## Description
The default metadata name was `ai-models.json`, this PR deprecates this
in favour of `anemoi.json` with a warning logged to the console.
Logging was done as this should be a seemless change for users with old
checkpoints working fine.

## Description

Last PR of 2025! (Or first of 2026 for people down under). A small
update of the `gather_provenance_info()` function:

- As Python 3.9 is not supported anymore, make full use of the
`importlib.metadata` package, which is the recommended way of finding
packages information, such as their version.
- Filter out system packages properly.
- Correctly report independently installed sub-packages (e.g.
`earthkit.data` vs `earthkit`, the latter being a package and not a
namespace).
