try installing go1.20 on Windows

The TestFromDirSymlink test is failing on Windows;

    === Failed
    === FAIL: fs TestFromDirSymlink (0.01s)
        ops_test.go:55: assertion failed: directory C:\Users\circleci\AppData\Local\Temp\test-from-dir-992742947 does not match expected:

              target: expected C:\some\inexistent\link got \some\inexistent\link

Unlike Linux, Windows is always testing against "latest" version of Golang;

    Chocolatey v2.2.2
    Upgrading the following packages:
    golang
    By upgrading, you accept licenses for the packages.

    You have golang v1.22.2 installed. Version 1.23.0 is available based on your source(s).
    Progress: Downloading golang 1.23.0... 100%

Try installing go1.20 to see if that's related
