fix: resolve YAML syntax errors in create-release workflow

Replaced heredocs with echo statements to avoid YAML parsing issues.
The YAML parser was interpreting markdown headings and other content
within heredocs as YAML syntax, causing validation errors.

Using grouped echo statements ({ echo ...; } > file) works correctly
with GitHub Actions YAML parser while maintaining variable expansion.
