[PATCH EDK2 v1 1/1] edksetup.sh:The version compare issue in shell script

["wenyi,xie" <xiewenyi2@huawei.com>]

REF:https://bugzilla.tianocore.org/show_bug.cgi?id=3948

In function of SetupPython3, the version of python will be
compared to get the new one. When python 3.10 is compared with
python 3.4, the result is not right. Because the version number
is treated as a float and 3.10 is smaller than 3.4.
So using sort to arrange the version from old to new in order
to get the new one.
