--out casing changed with release 0.27

[sosthene-nitrokey]

This may not be a bug, but it's not mentioned the release notes or in the commit message that introduced this so I'm not sure it's intentional.

The casing of the arguments of the --out parameter changed with the migration to Clap v4 in d1bd48e. This means that old scripts using --out Html will fail (expecting --out html).
This is changed because ValueEnum defaults to kebab-case.

This is not necessarily a bug, but it is an undocumented breaking change.

If this is not intentional (or even if it is), I think it would be great to support both casing for a while to ease the transition, maybe with a deprecation warning. This makes it easier for scripts to migrate to the new version progressively.

This is unintentional
