[Fix] nvm_resolve_local_alias: avoid using variable as printf format string

Using a variable as the format string means `%` characters in alias names would be interpreted as format specifiers. Use `%b` format with the variable as an argument to safely interpret `\n` escapes. Bug introduced in https://github.com/nvm-sh/nvm/commit/9b91734f0b6a210f0c6655b0cd25ea288d9ae376.
