Kitty inactive tab title.

Hello, I was going through kitty docs, and found out that there is no way to set an inactive tab title.
I think it might be an useful to keep track of tab numbers.

active_tab_title_template and tab_title_template together allow specifying different templates for active and inactive tabs if needed.

Thank you, that fulfills my needs.
