feat(react): preserve newlines during string formatting

[Garbanas]

Description

In @lingui/react, newlines in translations are not preserved during formatting (rendering), when <tags> are present.
Please see this demo: https://codesandbox.io/p/devbox/infallible-cdn-y863cd
This PR ensures that formatting is done the same way for both variants: with and without <tags>.
