1.3.76 broke possibility of injecting a chain spec path directly

[girazoki]

In tanssi we provide a custom-made chain-spec-path directly to zombienet, which was working until version 1.3.75. However after 1.3.76, and particularly after #1471, this possibility is no longer working. I am attaching a zip file with both zombienet versions, binaries and the configuration file that we use. It is linux based:

Unfortunately github does not allow me to upload files bigger than 25MB, so I will leave the configuration and the spec file. The tanssi binary can be downloaded from https://github.com/moondance-labs/tanssi/releases/download/v0.3.0/tanssi-node

zombieTanssi.json
tanssi-1000.json

Output after 1.3.76 when doing ./zombienet-linux-x64_1_3_76 spawn --provider native zombieTanssi.json
