Add context menu item to relaunch terminals with extra environment info

[ulugbekna]

Currently, when launching VS Code I often see terminals (including ones that just run tasks) have warnings that some terminal env contributions couldn't happen, so I need to relaunch the terminal.

Since the orange warning is quite eye-catching and distracting, I relaunch those terminals, but it's quite tedious because it can be done either using a link within hover, which is easy to lose on inaccurate mouse move and also non-keyboard friendly, or by killing and relaunching the terminal.

To alleviate this problem, could we add right-click context menu items to

• relaunch a specific terminal
• relaunch all terminals (including tasks)

This has become quite a pain point for me when I very often get these warnings and have to kill all terminals one by one and relaunch them (this's necessary for terminals with tasks running)

I also wonder if there could be false positives because in the hover I see both git contribution info but also that it couldn't contribute:

Should the wording then be "Would like to update its environment"? I think it's confusing and bug-like that git has already contributed to enable git auth provider but wants to relaunch to contribute again to enable git auth provider.
