fix(s3): remove customer encryption key from SSE-C debug log (#8875)

* fix(s3): remove customer encryption key from SSE-C debug log

The debug log in validateAndParseSSECHeaders was logging the raw
customer-provided encryption key bytes in hex format (keyBytes=%x),
leaking sensitive key material to log output. Remove the key bytes
from the log statement while keeping the MD5 hash comparison info.

* Apply suggestion from @gemini-code-assist[bot]
