Allow customizing messages in `cmd/serv.go`

Feature Description

Allow customizing responses sent to clients from cmd/serv.go, especially messages from this switch block:

func runServ(c *cli.Context) error {
    // ...
    switch key.Type {
    case asymkey_model.KeyTypeDeploy:
        println("Hi there! You've successfully authenticated with the deploy key named " + key.Name + ", but Gitea does not provide shell access.")
    case asymkey_model.KeyTypePrincipal:
        println("Hi there! You've successfully authenticated with the principal " + key.Content + ", but Gitea does not provide shell access.")
    default:
        println("Hi there, " + user.Name + "! You've successfully authenticated with the key named " + key.Name + ", but Gitea does not provide shell access.")
    }
    // ...
}

This would be useful for both localization as well as adding custom branding.

Screenshots

$ ssh -T git@GIT_SERVER
Hi there, USER_NAME! You've successfully authenticated with the key named KEY_NAME, but Gitea does not provide shell access.
If this is unexpected, please log in with password and setup Gitea under another user.

It's a small change. Maybe you can hold them in your fork. I don't think it's necessary to have a configuration for that.

I would argue that It'd still be useful for rebranding a custom Gitea instance. It'd be great if it took APP_NAME from the custom/conf/app.ini or something like that.

If you would like to rebrand, you would need to change a lot, but not only these strings. Theoretically you have to maintain your own changes.

APP_NAME is for the whole instance's name, it isn't for rebranding.

• the instance is a Gitea instance, its name is APP_NAME, just like a phone is an Android(or iOS) phone, its name is "Xxx's Phone".
