Ignore cdi-api pre-releases

Observed patterns include:

* 2.0-PFD2
* 2.0-PFD
* 2.0.Beta1
* 2.0.Alpha6
* 2.0.Alpha5
* 2.0.Alpha4a
* 2.0.Alpha4
* 2.0.Alpha3
* 2.0.Alpha2
* 2.0.Alpha1
* 2.0-EDR2
* 2.0-EDR1
* 1.1.PFD
* 1.1.PRD
* 1.1.EDR1.2
* 1.1.EDR1.1
* 1.1.EDR1
* 1.0-CR4
* 1.0-CR3
* 1.0-CR2
* 1.0-CR1

Usage of dot versus dash is inconsistent, as is usage
of "1" suffix versus no numeral (e.g. EDR1 vs PFD).

Where PFD might mean "proposed final draft"?
And PRD might mean "proposed release draft"?
And EDR might mean "early draft release"?
And CR might mean "candidate for release"?
It's fun to speculate.
