Play Framework

fix: SettingsParser regex now accepts classifier syntax (release 1.12.10)

PF-57's dependencies.yml introduced classifier-bearing entries
(e.g. "io.netty -> netty-codec-native-quic 4.2.12.Final osx-aarch_64").
YamlParser already accepted that syntax, but SettingsParser uses its own
regex for the contains: list in repository definitions and rejected the
4-token format with "Unknown dependency format -> ...".

The contains: list flows through SettingsParser separately from the
require: list because of the *allDependencies YAML anchor — every entry
gets parsed by both parsers. SettingsParser only needs to map repo->module
for resolution routing, so it accepts the optional classifier token but
discards it.

Without this fix, any project that depends on play 1.12.9 fails at
"play deps --sync" with the malformed-descriptor error because the
framework's own dependencies.yml fails to parse during repository setup.
