Llamacpp-python/run:Remove duplicated ] causing broken GPU test (nf-core#11573)

* Remove duplicated `]` causing broken test

* Add missing opening triple-quote in setup block

The setup block's HUGGINGFACE_DOWNLOAD process was missing the opening
""" before input[0] = [, leaving the closing """ orphaned and causing
the Groovy parser to fail with "Unexpected character: '\"'".
