This commit modifies thread-cert scripts utilizing `pktverify` to adopt a more flexible approach to TLV type checking. Specifically, it replaces strict equality (`==`) or strict subset (`<`) checks with a subset or equal check (`<=`) when verifying the presence of TLVs in a message. This adjustment ensures that test scripts adhere to the principle of ignoring extra or unknown TLVs, thereby future-proofing them against potential protocol updates that might introduce new TLVs.

# Router_1 is configured as Border Router for prefix 2001:db8:1::/64.
|

# Router_2 is configured as Border Router for prefix 2001:db8:1::/64.
|
