[careyyoung]

Describe the bug
依赖版本：
github.com/rookie-ninja/rk-boot/v2 v2.2.22
github.com/rookie-ninja/rk-cache/redis v1.2.17
github.com/rookie-ninja/rk-db/mongodb v1.2.18
github.com/rookie-ninja/rk-db/redis v1.2.18
github.com/rookie-ninja/rk-entry/v2 v2.2.22
github.com/rookie-ninja/rk-gin/v2 v2.2.23
现象：

1. 使用了配置文件：
2. 获取配置：rkentry.GlobalAppCtx.GetConfigEntry("config").GetBool("key1.enable")
3. 如果使用环境变量：key1_enable，覆盖不了配置文件中的值，
4. 需要使用key1.enable，才能覆盖
5. 应该是：github.com\rookie-ninja\rk-entry\v2@v2.2.22\entry\config_entry.go
   该行：entry.Viper.AutomaticEnv() 前 缺少调用：entry.Viper.SetEnvKeyReplacer(strings.NewReplacer(".", "_"))

期望结果：
使用环境变量：key1_enable，可以覆盖配置文件中的值
