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:

PySceneDetect/scenedetect/_cli/__init__.py

Lines 1031 to 1032 in 727f94b

	if ctx.command.name == "save-html":
	logger.warning("WARNING: export-html is deprecated, use save-html instead.")

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