[Flag] - Shows the Flag of Taiwan when try to use Burmese Flag #7122

Description

Was reading the documentation here: https://react.semantic-ui.com/elements/flag/#types-flag

but realized that the main example uses the Taiwan flag but in the code, it says Myanmar

Testcase

Expected When using Myanmar flag:

Instead of Showing 🇹🇼 should show 🇲🇲 Result Currently shows 🇹🇼 when using the Myanmar flag

[syang0624]

Most of the add/deletion is based on the rc settings from the original library to just make css prettier.

However, the key update here is: SemanticUI was showing 🇹🇼 when the user wanted a Burmese flag. It should show 🇲🇲

Fixed with this PR!
