Updates were rejected because the remote contains work that you not have locally.
翻译过来就是 更新被拒绝，因为远程包含了你本地没有的工作。
这通常是由于另一个版本库推送了

如何解决：
1.确保你当前的分支（release/R20220406）已经是最新的代码
并且，有可能其它分支commit到这个分支，却没有push到这个分支，所以简单的git pull是没有用的。

git pull origin release/R20220406 --allow-unrelated-histories

所以我用了这行命令将不管是commit还是push的东西全都拉取下来

然后重新commit后，重新push就解决问题了

git push origin HEAD:release/R20220406
