.NET 7.0.100 `dotnet test` cannot parse MSBuild switches from .rsp or command line if .NET CLI language is not `en`

Description

dotnet test command cannot parse parameters from provided .rsp file if .NET CLI language is de or ru but works fine with en on .NET SDK 7.0.100. It leads to an error Unrecognized command or argument ...

This bug is not reproducible on the .NET SDK 6.0.402.

To Reproduce

1. Create any test project in my case it’s xUnit project targeting net7.0. (please, check test project detail below)
2. Create any 1.rsp file with at least one switch, for example

-p:abc=123

1. Set environment variable DOTNET_CLI_UI_LANGUAGE to value de (German). In PowerShell

PS > $env:DOTNET_CLI_UI_LANGUAGE = 'de'

1. Running the following command

PS > dotnet test .\xUnit.Tests.csproj `@1.rsp

gives

Befehl oder Argument "-p:abc=123" nicht erkannt
