For CVE-2026-3783:
Refactored the test suite according to v8.11.1
crlf="headers" in tests/data/test2006 is a v8.19.0-only test framework feature and will fail for v8.11.1 as the value "headers" is not defined in this version. It has been introduced in v8.17.0
curl-8_19_0/docs/tests/FILEFORMAT.md

We have curl of version 8.11.1, According to the curl test suite file format 8_11_1/tests/FILEFORMAT.md, the crlf only takes one value that is "yes". So, refactored according to v8.11.1
