Custom Module Manager does not show extensions of its version correctly, e.g 1.0.0-alpha.1 is shown as 1.0.0

[Jefferson49]

Observed with v1.0.0-alpha.1 and webtrees 2.2.1

Custom Module Manager shows that a version 1.0.0 is available. However, it should be 1.0.0-alpha.1

The same can be observed in the custom module list of Custom Module Manager

[Jefferson49]

The same applies to other Jefferson49 webtrees custom modules
