Show tab numbers in tab-bar

[azarmadr]

Hi.
It will be nice to

• show tab numbers in tab-bar
• or have a configuration that shows tab numbers
• or show when ctrl t is pressed.

Like the following

As a workaround, I created a new plugin by copying default_plugin/tab-bar and change two lines.
diff '--color=auto' -u -d zellij/default-plugins/tab-bar/src/main.rs zellij-numbered-tab-bar/src/main.rs

         let mut is_alternate_tab = false;

+        for (i,t) in self.tabs.iter_mut().enumerate() {

             if t.active && self.mode_info.mode == InputMode::RenameTab {

I don't want to maintain a new plugin with just two lines different. Can it be in default_plugins in any way?
