System information

tools version: 3.4.0.dev0

Reproduce the failure with nf-core modules create using tools version 3.4.0.dev0, then inspect the generated modules/nf-core/seq2hla/meta.yml around the versions output. Run the reported Prettier hook against the created files; done means module creation completes without the YAML syntax error and the generated files are formatted successfully.
