setting rotate by count , do not clear first file

[xieyj-apple]

create logfile by day:

w, err := rotatelogs.New(
"/path/log/test.log.%Y%m%d",
rotatelogs.WithLinkName("test.log"),
rotatelogs.WithRotationCount(10),
rotatelogs.WithRotationSize(10*1024))
if err != nil {
golog.Fatal(err)
}

finally:

test.log.20230404
test.log.20230404.30
test.log.20230404.31
test.log.20230404.32
test.log.20230404.33
test.log.20230404.34

and why do RotationCount and MaxAge can not effective together
