We should update the README.markdown rather than the wiki

Thanks! I moved the doc to the README.markdown now.
Adds the cosocket-level plumbing for a new tcpsock:settrustedstore(store) method, allowing Lua code to supply a per-handshake X509_STORE that overrides lua_ssl_trusted_certificate for the upcoming sslhandshake(). This is needed for use cases where the set of trusted CAs is determined at request time (e.g. per-tenant mTLS upstreams). * a new X509_STORE *ssl_trusted_store field on ngx_http_lua_socket_tcp_upstream_t, used as a one-shot slot consumed by the handshake; * the FFI entry point ngx_http_lua_ffi_socket_tcp_settrustedstore() that validates the cosocket state and stores the pointer on the upstream; * SSL_set1_verify_cert_store() invocation inside ngx_http_lua_ffi_socket_tcp_sslhandshake() when a store has been set, with the slot cleared after use so it cannot leak across handshakes. The matching tcpsock:settrustedstore() Lua wrapper will land in lua-resty-core in a separate change. Signed-off-by: Walker Zhao <walker.zhao@konghq.com>
