Why is this an error rather than a no-op or warning?

```julia
Pkg.upgrade_manifest()'
ERROR: Format of manifest file at `C:\Users\Mark Nahabedian\NahaJuliaLib.jl\Manifest.toml` already up to date: manifest_format == 2.0.0

I agree with this, and I am bringing this old post up again, as this still exists on Julia v1.9.0-beta4. This isn’t an error from a user perspective, and the stacktrace seems like internal implementation details that users shouldn’t need to care about in this specific context.
