go 版本依赖

[shuqingzai]

在 v4.13.0 开始需要 go1.22+ ，这对于生产环境过于激进，是否可以跟随 Go policy 保持最新两个维护版本可用？这样可以使受众面更广

We also use go-redsync in a project where we follow the Go policy and therefore support Go 1.21 and 1.22. Since I don't see a technical reason to bump to 1.22, we would appreciate it if this project could also follow this approach.
