Action is ~2845% slower on windows

[arthurfiorette]

Take a look at the below CI run for example:

https://github.com/kitajs/kitajs/actions/runs/8508120067

The same CI takes 6 minutes more on windows.

On linux, the codecov step takes 11 seconds.
On macos the same step takes 29 seconds.
But on windows it takes 5 minutes and 13 seconds!! That's too much!
