This PR adds missing documentation for the samesite attribute in the http.cookies module.
While the attribute was already listed among valid Morsel attributes, it lacked an explanation. This change adds clear and complete documentation explaining:
-The attribute’s role in CSRF protection.
-The valid values: "Strict", "Lax", and "None".
-The requirement that "secure" must be set when using "SameSite=None".
This update brings the documentation in line with RFC6265bis and reflects current browser behaviour.
