.NET 9 terminal logger litters output with "Build succeeded" on commands that do not build anything

### Describe the bug
After upgrading to the .NET 9 SDK, build scripts issuing `dotnet` commands litter the output with `Build succeeded in X.Xs` even for commands other than `dotnet build`.

### To Reproduce

For an example, see `build.ps1` in a representative repo at https://github.com/fixie/fixie/blob/ca6aac79f8a6dcec2b4abf58c537abca94a2b251/build.ps1

- `dotnet clean...` is now followed by "Build succeeded in..." where it was not before.
- `dotnet $fixie...` where $fixie is the path to a built dll, simply executing it, is now followed by **TWO** occurrences of "Build succeeded in..." where none were output before. I suspect this is because the first invocation is the one witnessed in the build script, and then the second is likely because the invoked executable itself is issuing a `dotnet` command to run a secondary dll in the same fashion via `ProcessStartInfo`.
- `dotnet pack...` is now followed by "Build succeeded in..." where it was not before.

Proof that this output did not happen before can be seen in the Build section of this github actions job: https://github.com/fixie/fixie/actions/runs/11688386793/job/32548703947

This change to the output can only be confusing for non-build commands, and if we have to start littering all of our commands with something extra to suppress it by adjusting verbosity (and accidentally suppress substantive other details), then the phasing out of the explicit `--tl` was a net loss.
