Improve version expression reason

[BernieWhite]

For the case:

field: properties.grafanaMajorVersion
version: '>=10'

The outputted reason is Path properties.grafanaMajorVersion: The version '9.-1.-1' does not match the constraint 'PSRule.Data.SemanticVersion+VersionConstraint'.

This could be improved by:

• Handling the -1 when the value is just 9 instead of 9.0.0.
• Fix the string formatting for the constraint.
