[Issue] Update Curl to respect case-insensitive headers

[m2-assistant]

This issue is automatically created based on existing pull request: #29274: Update Curl to respect case-insensitive headers

---

According to RFC 2616 header names are case-insensitive: "Each header field consists of a name followed by a colon (":") and the field value. Field names are case-insensitive." - see https://tools.ietf.org/html/rfc2616#section-4.2

The "Set-Cookie" comparison in the current Curl client is case-sensitive and can cause problems with some (rare) HTTP servers.
