tonic-reflection 0.12.x moved from the v1alpha to v1 of the reflection
protocol.
However, most clients, like Postman, Kreya and evans don't support that
one yet.
Bump tonic-reflection to 0.12.2, which re-introduces v1alpha support
alongside the v1 version of it, registering both services.
This fixes the example documented in tvix/store/README.md, it was
previously failing as evans couldn't find the v1alpha reflection
service.
See https://github.com/hyperium/tonic/pull/1888 for details.
