i18next: TFuncKey type breaks when used in Record and Map types

🐛 Bug Report

Use TFuncKey in a Record or Map type, and the outputted type from t(recordOrMapKey) will not be string.

To Reproduce

https://codesandbox.io/p/sandbox/elastic-burnell-wm183x?file=%2Fsrc%2FApp.tsx

Notice that there are TS errors at the bottom of <Component> and <App>, and that t(recordKey) and t(mapKey) equal 'string | { bar: string; }'.

Two curious observations:

1. Commenting out the nested foo string causes all TS errors to go away.
2. t(key) also errors out when used in a function Foo() {} component instead of a const Foo = () => {} component. Not sure what the difference is there.

Expected behavior

The TS type from t(recordKey) and t(mapKey) should equal string.
