doc: add a tip about developer mode on Windows

On Windows, creating symlinks requires Developer Mode to be
enabled or running the command as Administrator. Tests that
rely on creating symlinks may fail with EPERM errors if
symlink creation is not permitted. Add a tip about this
for the docs about running tests on Windows.
