Project thread: pcTzPl-2Cf-p2

This PR implements the 📌 Move tax setting to main setting page task of the project.

• The tax rate setup has been hidden by Streamline onboarding: Conditionally hide the tax setting #2542 in the onboarding flow, and it should remain hidden after moving the setup. Therefore, the tax rate setup is completely removed from the onboarding flow.
• The tax rate setup is moved from the Edit free listings page to the Settings page.

💡 Update for src/Tracking/README.md will be done by the conjunction PR for the feature branch.

Screenshots:

WDYT about adding a confirmation message as feedback when the Setting save is completed.

Thanks @eason9487 for working on this. I didn't found any blocker so far. Just a recommendation about adding a message after saving taxes setting. Not sure if this was already discussed with Design. In any case not a strong blocker for me and can be done also in further PRs

• Tested the Taxes Section is not shown in Edit Free listings ✅
• Tested the Edit Free listings still work and can be saved ✅
• Tested the Taxes Section is not shown in Settings when neither US is the store base address nor a audience target country ✅
• Tested the Taxes Section is shown in Settings when either US is the store base address or a audience target country ✅
• Tested you can save the taxes and it calls the API endpoints ✅
• UI general checks
• Code & Tests checks
• Additional Onboarding check
