make the levels consistent for correlation referenced rules

[YamatoSecurity]

I noticed that if you run Hayabusa with a minimum alert level of say medium, then the correlation rules with a level of medium will get a parsing error because the referenced rules were set to informational

Ex:

[WARN] Failed to parse rule. (FilePath : rules/hayabusa/builtin/Security/LogonLogoff/Logon/Sec_4648_Med_ExplicitLogon_PW-Spray_Correlation.yml) The referenced rule was not found: explicit_logon
[WARN] Failed to parse rule. (FilePath : rules/hayabusa/builtin/Security/LogonLogoff/Logon/Sec_4625_Med_LogonFail_UserGuessing_Correlation.yml) The referenced rule was not found: non_existent_user
[WARN] Failed to parse rule. (FilePath : rules/hayabusa/builtin/Security/LogonLogoff/Logon/Sec_4625_Med_LogonFail_WrongPW_PW-Guessing_Correlation.yml) The referenced rule was not found: incorrect_password

Since the referenced rules are only meant to be outputted when debugging the rule, I think I will just make sure the referenced rules have the same level as the correlation rule.
