The elixir-binary and elixir-library classifiers' regexes only matched
the bare semver triplet (and a single sub-segment for the library), so
release-candidate elixir images were either missed entirely or had
their version truncated:
$ syft -q elixir:1.12.0-rc | grep elixir # nothing
$ syft -q elixir:1.13.0-rc.0 | grep elixir
elixir 1.13.0 binary # truncated, "-rc.0" lost
Extend the version capture group to optionally include
"-<a-z0-9>+(\\.<digits>)?" so "1.12.0-rc.1", "1.13.0-rc.0", etc. match
exactly as the elixir.app and the binary's ELIXIR_VERSION line have
them.
Add a logical fixture under testdata/classifiers/snippets/elixir/
1.12.0-rc.1/linux-amd64 (cloned from the existing 1.19.1 fixture with
just the version strings changed) and register it in
Test_Cataloger_PositiveCases.
