[wheel] fix windows wheel building (ray-project#58343)

add `--use-pep517` flag; otherwise some part of the wheel building logic
does not work on windows python 3.12

also removes the unnecessary "uninstall+reinstall" dance. the script
only builds the wheel, it does not (and should not) install the wheel.
