localstack extensions install fails under Windows

Nobody has claimed this yet.

I am unable to download the extension.

` localstack extensions install "git+https://github.com/localstack/localstack-extensions/#egg=localstack-extensions-stripe&subdirectory=stripe"`

```
C:\LocalStack>python "C:\Users\marce\AppData\Local\Programs\Python\Python310\Scripts\\localstack" extensions install git+https://github.com/localstack/localstack-extensions/#egg=localstack-extensions-stripe

The above exception was the direct cause of the following exception:

Reproduce the extensions install command on Windows, then trace the failure through localstack_ext/cli/extensions.py and localstack/utils/container_utils/docker_cmd_client.py. Check the Docker start error and the shell's handling of the extension URL. Done means the extension installs successfully without the container path or command parsing errors shown here.
