• Support ilc_url_for_version support for v00-04-pre patch levels

ENDRELEASENOTES

Until now, we had:

$ spack versions marlindd4hep 
==> Safe versions (already checksummed):
  master  0.6.2  0.6.1  0.6
==> Error: %d format: a real number is required, not VersionStrComponent

but with this fix we have:

$ spack --backtrace versions marlindd4hep ==> Safe versions (already checksummed):
  master  0.6.2  0.6.1  0.6
==> Remote versions (not yet checksummed):
  00-05  00-04-pre  00-04

This allows for better programmatic version parsing support.
