this change addresses a regression introduced by 92494911.
in 92494911, we tried to set $SCYLLA_VERSION with env.RELOC_VERSION, but github action does not allow this. because the env variables in github's workflow YAML are expanded when the YAML file is parsed. so SCYLLA_VERSION is never expanded with the value of RELOC_VERSION.
so, in this change, to avoid the repeatings, we use environmental file to store SCYLLA_VERSION, so that it can be picked by the steps that consume this env var.
