"No Changes to `~/PkgA/Manifest.toml`" is misleading since there can be changes

This is a "known" issue but I couldn't find it filed anywhere. If `resolve` fixe…s the dependencies of a dev'd package in a way that doesn't add new dependencies to the overall Manifest, then "no changes" are reported, even if the Manifest is indeed changed. ```julia ❯ julia -q (@v1.7) pkg> generate PkgA Generating project PkgA: PkgA/Project.toml PkgA/src/PkgA.jl (@v1.7) pkg> generate PkgB Generating project PkgB: PkgB/Project.toml PkgB/src/PkgB.jl (@v1.7) pkg> activate PkgB Activating project at `~/PkgB` (PkgB) pkg> add Dates Updating registry at `~/.julia/registries/General.toml` Resolving package versions... Updating `~/PkgB/Project.toml` [ade2ca70] + Dates Updating `~/PkgB/Manifest.toml` [ade2ca70] + Dates [de0858da] + Printf [4ec0a83e] + Unicode Precompiling project... 1 dependency successfully precompiled in 1 seconds (PkgB) pkg> activate PkgA Activating project at `~/PkgA` (PkgA) pkg> dev ./PkgB Resolving package versions... Updating `~/PkgA/Project.toml` [1821aa1f] + PkgB v0.1.0 `../PkgB` Updating `~/PkgA/Manifest.toml` [1821aa1f] + PkgB v0.1.0 `../PkgB` [ade2ca70] + Dates [de0858da] + Printf [4ec0a83e] + Unicode ``` Ok, now we have PkgA which dev's PkgB, which depends on Dates. All is well. Now edit PkgB to do `using Unicode`. Then ```julia > julia -q --project=PkgA julia> using PkgB [ Info: Precompiling PkgB [1821aa1f-13ce-41b2-bd12-ba9ec74d35d8] ┌ Warning: Package PkgB does not have Unicode in its dependencies: │ - If you have PkgB checked out for development and have │ added Unicode as a dependency but haven't updated your primary │ environment's manifest file, try `Pkg.resolve()`. │ - Otherwise you may need to report an issue with PkgB └ Loading Unicode into PkgB from project dependency, future warnings for PkgB are suppressed. ``` Ok, we need to add Unicode to PkgB's deps and resolve: ```julia (PkgA) pkg> activate PkgB Activating project at `~/PkgB` (PkgB) pkg> add Unicode Resolving package versions... Updating `~/PkgB/Project.toml` [4ec0a83e] + Unicode No Changes to `~/PkgB/Manifest.toml` (PkgB) pkg> activate PkgA Activating project at `~/PkgA` (PkgA) pkg> resolve No Changes to `~/PkgA/Project.toml` No Changes to `~/PkgA/Manifest.toml` ``` No changes to the manifest or project! However, the problem has indeed been fixed: ```julia ❯ julia -q --project=PkgA julia> using PkgB ``` (no warnings). I think we should change "no changes" to something more accurate, like "No added or removed packages".

你装完包， ]st 能看见新的包么？这个包能用么？
按照 issue 里的说法，实际上是能用的，只是这个提示信息有误导。
