Fix: sometimes dnslog request record is uppercase caused by nuclei templates uneffective

[monitor403]

BackGround

Recently, when I was using nuclei to scan for vulnerabilities, I found that when nuclei was verifying dnslog-related vulnerabilities, I found that there would be uppercase of dnslog records leading to the failure of nuclei's templates regular matching, resulting in the inability to effectively detect the vulnerability
Picture1: dnslog Uppercase logs fail to detect vulnerabilities

Picture2: dnslog Lowercase logging detects vulnerability

Picture3: dnslog related templates can't match uppercase

Picture4: nuclei-templates

Proposed changes

Convert uppercase letters to lowercase to ensure proper detection.
