New desktop-linux / desktop-windows contexts cause problems when switching OS mode #11721

• I have tried with the latest version of Docker Desktop (I'm on 3.5.2)
• I have tried disabling enabled experimental features N/A
• I have uploaded Diagnostics N/A
• Diagnostics ID: N/A

Actual behavior

1. Start Docker Desktop for Windows on Linux containers mode.
2. Run docker context ls. There's two by default as of 3.5.0, default and desktop-linux.
3. Switch to desktop-linux with docker context use desktop-linux.
4. Switch to Windows containers.
5. Attempt any docker ... command. You get the error: Current context "desktop-linux" is not found on the file system, please check your config file at C:\Users\username\.docker\config.json. Even docker context use desktop-windows does not work, with the same error.
6. Switch back to Linux containers. The error still persists, even though this context does exist now!

The only way I've found to make the error go away is to manually edit ~/.docker/config.json by setting the context to default.
Note: You can reproduce the same behavior if you go from Windows containers -> Linux containers with desktop-windows.

This reproduces every time.

Expected behavior

1. Switching from Linux to Windows containers or vice versa should automatically switch from desktop-linux to desktop-windows or vice versa.
