http3/BadCipherSuiteErrorTest is a clone of http2/ErrorTest - adapted to replace HTTP/2 specifics with HTTP/3.
The original ErrorTest test had been introduced as a non regression test for JDK-8157105.
I guess we could consider merging BadCipherSuiteErrorTest with H3QuicTLSConnection if we are sure that path is covered. I have logged https://bugs.openjdk.org/browse/JDK-8365800
