Mise shell hook: data did not match any variant of untagged enum HookDef

[hur]

I'm having trouble with shell hooks on 2026.2.17 macos-arm64 (2026-02-19)

[hooks]
postinstall = [
  "krew install krew",
  "krewfile -file {{config_root}}/.krewfile",
]

[[hooks.enter]]
shell = "fish"
script = [
  "kubectl completion fish | source",
  "talosctl completion fish | source",
  "flux completion fish | source",
  "yq completion fish | source",
  "flux completion fish | source",
]

Results in error
