[DmitriyLewen]

Description

By default, we suppress Dev dependencies (npm, yarn is currently support only).
We need to show info about it.

What if showing the log message here? The downside is it is performed on the server side in client/server mode.

trivy/pkg/scanner/local/scan.go

Lines 422 to 432 in e1ea02c

	// excludeDevDeps removes development dependencies from the list of applications
	func excludeDevDeps(apps []ftypes.Application, include bool) {
	if include {
	return
	}
	for i := range apps {
	apps[i].Libraries = lo.Filter(apps[i].Libraries, func(lib ftypes.Package, index int) bool {
	return !lib.Dev
	})
	}
	}

This is not good. I think that users rarely check server logs. In this case, they can easily miss this information.

But after some thought i realized that your solution looks better because in my solution we will show this message even if the --include-dev-deps flag is enabled.

I will update PR.
