Doc Tapscript Example with Tap - Error: Invalid Script

[BowTiedDeployer]

https://github.com/bitcoin-core/btcdeb/blob/master/doc/tapscript-example-with-tap.md#generating-a-taproot-commitment
When running the example it gives an error about an invalid script instead of displaying it as on the doc example.

Tried on ARM chip Ubuntu and Intel chip Ubuntu.

tap $pubkey 2 $script_alice $script_bob
tap 0.4.22 -- type `tap -h` for help

+1 would really be helpful to understand this

The arguments when using bash instead of zsh have to be:

tap $pubkey 2 "${script_alice}" "${script_bob}"

Otherwise, an array argument is taken as multiple arguments instead of a single one.
