apacheGH-34296: [C++][CI] Force appveyor builds to use conda-forge an…

…d ignore defaults channel (apache#34297) For some reason (potentially related to mamba-org/mamba#656 or maybe just the default conda behavior) it appears that specifying `-c conda-forge` is not sufficient as conda will still check the defaults channel. Lately it seems the defaults channel has introduced some incompatibility that leads to a deadlock or hang during solve. This PR disables defaults completely which seems to avoid the hang. * Closes: apache#34296 Authored-by: Weston Pace <[email protected]> Signed-off-by: Jacob Wujciak-Jens <[email protected]>
