Incorrect deprecated command warning for `save-html`

[Breakthrough]

It looks like in v0.6.x after export-html was renamed to save-html, but backwards compatibility was kept with the prior. We emit the warning to use the new command name with the new command instead of the old one: https://github.com/Breakthrough/PySceneDetect/blob/727f94bd1048218e03728daf7e5d500e6bccfd23/scenedetect/_cli/init.py#L1031-L1032

The first line should check for the deprecated export-html name, but it matches the new save-html one instead.
