Docs for `up` is wrong

[KristofferC]

From the docs

If no positional argument is given, update all packages in the manifest if mode is PKGMODE_MANIFEST and packages in both manifest and project if mode is PKGMODE_PROJECT.

This doesn't really make sense because packages in the project is also in the manifest. And up -m also updates packages that are in the project:

(jl_xPuOsW) pkg> up -m
    Updating registry at `~/.julia/registries/General.toml`
    Updating `/tmp/jl_xPuOsW/Project.toml`
  [91a5bcdd] ↑ Plots v1.25.3 ⇒ v1.25.11
    Updating `/tmp/jl_xPuOsW/Manifest.toml`
  [28b8d3ca] ↑ GR v0.62.1 ⇒ v0.64.0
...

From the REPL doc on up:

Update pkg within the constraints of the indicated version
specifications. These specifications are of the form @1, @1.2 or @1.2.3, allowing
any version with a prefix that matches, or ranges thereof, such as @1.2-3.4.5.

(jl_C8ktCX) pkg> up Plots@1.25.3
    Updating registry at `~/.julia/registries/General.toml`
    Updating `/tmp/jl_C8ktCX/Project.toml`
  [91a5bcdd] ↑ Plots v1.25.3 ⇒ v1.25.11
...

@ does nothing.

It is also a bit strange that the docs for the API mode and REPL mode are so different.
