bug#44413: 28.0.50; Provide function to close the tab

[Jean Louis]

Instead of lambda anonymous function it would be more useful to
provide named function to close the tab. This way keybinding can be
customized easily. There exists function to open the tab, while
anonymous one is handling closing of the tab.

<tab-bar> <C-current-tab> runs the command (lambda nil (interactive)
(tab-bar-close-tab 6)) (found in global-map), which is an interactive
Lisp function.

(anonymous)

Not documented.
