WFA and ONTAP 9.10 upgrade type casting issue.

After ONTAP 9.10 upgrade, workflows containining the 'Create Volume' step (and possibly others) failed with the previous version test.

The problem turned out to be a typecasting issue in the Compare-Ontapversions function within the WFAWrapper PS module.

To fix, add typecastinfg to [int] the following lines in the Compare-Ontapversions function (137-138, 148-150).

Corrected code is below:

------------------

if($FirstVersion -match "^(?<major>\d+)[.](?<minor>\d+)[.](?<micro>\d+)$")
{
$major1 = [int]$matches.major
$minor1 = [int]$matches.minor
$micro1 = [int]$matches.micro
}
else
{
throw "The input FirstVersion is not in the expected format."
}

if($SecondVersion -match "^(?<major>\d+)[.](?<minor>\d+)[.](?<micro>\d+)$")
{
$major2 = [int]$matches.major
$minor2 = [int]$matches.minor
$micro2 = [int]$matches.micro
}
