Subject: [PATCH 025/147] Dont's use DTLS_MAX_VERSION when setting SSL_CTX

It was fixed quite some time ago for TLS counterpart (TLS_MAX_VERSION),
but somehow the similar fix was missing for DTLS. OpenSSL v3 deprecated
those constants and they can be compiled out by OPENSSL_API_COMPAT.

Pick-to: 6.2
Task-number: QTBUG-94596
Change-Id: Ia0246170a003db900c430b2fbfc177caf05a395a
