fix: call GatherEnvironmentInfo once in NodeAddToClusterMulti to avoi…
3b6c866 
…d race condition causing error

fixes k3d-io#1410

When multiple nodes are created, each call to NodeAddToCluster was calling GatherEnvironmentInfo,
which was calling EnsureToolsNode() and then deleting the tools node. This causes some type of race
condition. The work doesn't need to be done multiple times anyways, so just move it up to
NodeAddToClusterMulti and do it once, before kicking off the goroutines.
