[IMP] finance: remove fiscal localization countries screenshots

[StraubCreative]

Overview
Remove confusing screenshots for customers under Finance > Accounting and Invoicing > Fiscal Localizations section. Customers get confused by the screenshots of the country modules, as they think that those modules are the only country-supported modules we have (which makes more issues than not).

Summary of changes

• Remove country modules screenshots across localizations_list.rst and fiscal_localization_packages.rst
• Delete /media folder in /applications/finance/accounting/fiscal_localizations/overview which contain fiscal_localization_packages_selection.png and fiscal_localization_packages_modules.png

Outcomes

• Removed images will hopefully remove confusion for the customer and will be more likely to follow the text directions which encourage them to look through the entire modules list.
• Small page-speed improvement with lighter page weight.

LGTM but the commits need to be squashed into a single commit. Then we're good to go :)
