Increase Jest unit test coverage for the Swaps feature to ~25% (#10900)
* Swaps: Show a network name dynamically in a tooltip

* Replace “Ethereum” with “$1”, change “Test” to “Testnet”

* Replace 이더리움 with $1

* Translate network names, use ‘Ethereum’ by default if a translation is not available yet

* Reorder messages to resolve ESLint issues

* Add a snapshot test for the FeeCard component, increase Jest threshold

* Enable snapshot testing into external .snap files in ESLint

* Add the “networkNameEthereum” key in ko/messages.json, remove default “Ethereum” value

* Throw an error if chain ID is not supported by the Swaps feature

* Use string literals when calling the `t` fn,

* Watch Jest tests silently (no React warnings in terminal, only errors)

* Add @testing-library/jest-dom, import it before running Jest tests

* Add snapshot testing of Swaps’ React components for happy paths, increase minimum threshold for Jest

* Add the test/jest folder for Jest setup and shared functions, use it in Swaps Jest tests

* Fix ESLint issues, update linting config

* Enable ESLint for .snap files (Jest snapshots), throw an error if a snapshot is bigger than 50 lines

* Don’t run lint:fix for .snap files

* Move `createProps` outside of `describe` blocks, move store creation inside tests

* Use translations instead of keys, update a rendering function to load translations

* Make sure all Jest snapshots are shorter than 50 lines (default limit)

* Add / update props for Swaps tests

* Fix React warnings when running tests for Swaps
