See usage of StringParseUint or ByteExtractStringUint

ike-chosen-sa is not a pure integer,

typedef struct {
    char *sa_type;
    uint32_t sa_value;
} DetectIkeChosenSaData;

This ticket will remain about pure integers

https://github.com/OISF/suricata/pull/13998 did some

After https://github.com/OISF/suricata/pull/14043 only ip_proto will remain

Actually, I am not sure ip_proto is a good fit for the generic integer, as it gets used in signature DetectProto array, and can be used multiple times in a signature to refine (adding exclusions)
