[wasm] Add workaround NuGet-Migrations issue for a missed case (#87041

)

One case was missed in the earlier attempt at this, which caused some of
the tests in wasm runtime tests to not get the workaround script.

One such example - `JIT.PGO`

The other cases had:
```sh
export WasmTestAppArgs="$WasmTestAppArgs --exclusion-list=TestExclusionList.txt"
chmod +x ./RunTests.sh
(CONSOLE_TEMP_DIR="$(mktemp -d)" ; "$DOTNET_ROOT/dotnet" new console -o "$CONSOLE_TEMP_DIR" ; rm -rf "$CONSOLE_TEMP_DIR") || true
./RunTests.sh
```

.. and the broken one has:

```sh
dotnet $CORE_ROOT/xunit/xunit.console.dll profiler/unittest/profiler.unittest.XUnitWrapper.dll -parallel collections -nocolor -noshadow -xml testResults.xml -trait TestGroup=profiler.unittest
```

.. no workaround with `dotnet new ..`.
