Archetype version 39 states it's compatible with 6.5.7.0+ but will not accept later service pack release.

### Expected Behaviour
When typing 6.5.8 for the aemVersion property, expect it to accept the value.

### Actual Behaviour
It only accepts the following specific values: 6.4.8.4; 6.5.7; or cloud

### Reproduce Scenario (including but not limited to)
Run Maven archetype generate command and choose No (N) to enter each availably property individually.

#### Steps to Reproduce
Run mvn archetype:generate -DarchetypeGroupId=com.adobe.aem -DarchetypeArtifactId=aem-project-archetype -DarchetypeVersion=39 -DgroupId=(YOUR-GROUPID) -DartifactId=(ARTIFACTID) -DappId=(APPID)

At the "Conform properties configuration" prompt,
Select "N" to choose value of each available property.

For the aemVersion property, type 6.5.8

#### Platform and Version
AEM Project Archetype v.39

#### Sample Code that illustrates the problem

Define value for property 'aemVersion' (should match expression '^(6\.4\.8\.4|6\.5\.7|cloud)$') cloud: : 6.5.8
Value does not match the expression, please try again cloud: :

#### Logs taken while reproducing problem
N/A

Start by running the Maven archetype:generate command from the issue and inspect where the aemVersion validation expression is defined for archetype version 39. Update the accepted values so 6.5.8 is accepted, then rerun the interactive property prompt to verify the value passes validation.
