docs: Refactor command tab code

[romain-trotard]

Hello :)

Following the discussion on this issue #2640, I open this PR.

So I have extracted all the logic of command / tab selection in a hook named useBashCommand. And watch the command directly in the DocsCodeBlock component to refresh the data to copy.

Hopefully I did not have to extract the tabState logic of the RowingTabs component :)

Note: Most of the code of useBashCommand is the same that the old getBashCommand file.

Note: On master, it seems to have a bug with the animation of tabs when going fast on selection (the problem is not added by this PR) :

Hello @SamuraiF0x

Yes I hadn't solve the problem, I thought to do it on another PR.
However, I took some times and found the problem, so I push it on the second commit ;)
