添加标签(tag)

添加tag语法：
git tag -a <tag name> -m <tag message>

强制更新本地tag

加上 -f 选项即可，全称 --force
git tag -f -a <tag name> -m <tag message>

> git tag -f -a 1.0.3 -m "changed `<en-todo>` tag to `<input>`"
Updated tag '1.0.3' (was 1f1e147)

强制更新远程仓库tag

如果直接推送本地更新过的tag到远程服务器，会被服务器拒绝：

> git push origin master --tags

error: failed to push some refs to 'https://github.com/dexfire/markdown-it-todo'
hint: Updates were rejected because the tag already exists in the remote.

这时我们同样需要强制推送，更新远程tag，同样增加-f选项即可：
git push origin master --tags --force
