* Refactor install page (db type) * set correct default DB HOST for different DB TYPE * remove legacy TiDB from documents * unify the usage of DB TYPE, in code we only use "mysql". "MySQL" is only shown to users for friendly name. * Gitea can use TiDB via MySQL protocol Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lunny Xiao <xiaolunwen@gmail.com>
