update torch dependency for mac/linux compatibility

[Anxhela21]

Description

In LCORE evaluation we are temporarily depending on road-core dependencies. The road-core service has hard requirement for torch version 2.7.0+cpu which is incompatible for mac (requires 2.6.0). In this PR we remove torch from main dependencies and instead define platform-specific versions under optional dependency group

in order for tests to pass on CI, the lockfile should be generated for "default", "dev", and also probably "evaluation" groups (and now for "torch-linux"). It might fix CI failures.
