gegles-spdlog_setup: relax fmt version constraint to allow 12.x (#28751)

* gegles-spdlog_setup: relax fmt version constraint to allow 12.x

Resolves dependency conflict with spdlog/1.16.0 which requires fmt/12.0.0.
The library is compatible with fmt 12.x as a header-only wrapper around spdlog.

Fixes #28736

* Update recipes/gegles-spdlog_setup/all/conanfile.py
