Launch/OpenUrl API is broken on Windows with 7.1+

[ivankravets]

Expected Behavior

click.launch() API is broken with 7.1 on Windows. We are going to have a quick release of @platformio and lock Click to <7.1. Something is going wrong with Click last time.

>>> import click
>>> click.__version___
>>> 7.1.1
>>> click.launch("https://github.com?click_7_1=is_broken")
>>> The system cannot find the file 'https://github.com?click_7_1=is_broken'
>>> 1

Actual Behavior

Everything works on Click < 7.1. See changes:

• https://github.com/pallets/click/blob/7.0/click/_termui_impl.py#L503
• https://github.com/pallets/click/blob/master/src/click/_termui_impl.py#L560

Environment

• Python version: No matter
• Click version: 7.1+

Looks like 7.1 broke mssql-cli for us on Windows.

We have a thread tracking the bug here.
