chore(size-limit): test esm packages and update size-limit dep

[timofei-iatsenko]

All bundlers actually consume ESM version of packages. CJS version is usually used by nodejs. So it's make more sense to test ESM versions for the size because it will bundled and shipped to the browser.

I had to rise the limit for @lingui/core package to 5.5kb. It's not related to CJS/ESM change, it's related to size-limit dependecy update. It uses fresher bundlers which generate a slightly bigger results for both targets (CJS/ESM) i've tested it both with esbuild and webpack bundlers.

@thekip What does the upgrading of size-limit bring us? The "import" config works in also in the previous version.
The only change I see is that our package has grown over 5 kB. And if that's the only impact it has, I think we should not update the size-limit package.

[timofei-iatsenko]

@Martin005 do you really understand how this package works? Please read the docs, and improve your understanding what exactly size-limit doing and where exactly this 5kb appeared.

@thekip please briefly explain it here

[timofei-iatsenko]

This change did not increase actual size of the package. This affects only reporting of the size by size-limit lib. It becomes more accurate because now uses fresher versions of bundlers to calculate a size.

Rebased to main and add "react" as "external". Because we assume every app which going to use @lingui/react would already have react in the bundle, so we should not take it into account in budget calculation.
