* flutter-build.yml: drop workarounds for flutter 3.13
@fufesou has removed them from build_fdroid.sh in #10040 but
forgot to remove them in main flutter_build.yml. flutter 3.13
is not used anymore, and those who want to build the old version
using flutter 3.13 can happily check out the appropriate commit
from Git history.
* Bump vcpkg baseline to 2025.01.13
@linsui addressed the missing vcpkg-tools.json file inside vcpkg
revision (microsoft side, not rustdesk's!) by updating the vcpkg
baseline.
