misc(NavigationTab): use Tailwind

[ansmonjol]

Context

We're migrating our codebase to replace styled component by tailwind (TW)

Description

This PR does migrate the NavigationTab component to use TW internally.
During the process, it's API and internal behaviour slightly changed:

• The component does not contain extra wrappers. Meaning that it renders the Tabs component followed by the Tab content directly in the DOM
• By doing so, it allows to pass a className directly to the Tabs and remove the leftSpacing API in favour of simple TW class usage
• By default the wrapper has no padding, so all leftSpacing={0} can simply be removed without further action

Fixes LAGO-425
