Bumps react-i18next from 17.0.16 to 17.0.19.

Changelog

Sourced from react-i18next's changelog.

17.0.19

• fix: useTranslation with an inline selector keyPrefix (useTranslation('ns', { keyPrefix: ($) => $.role })) returned a new t on every render, so every effect, useCallback and useMemo depending on t ran again each time. The cached t was compared against the keyPrefix function itself, and an inline arrow is a new function on every render. It is now compared against the key the selector resolves to (with the same options and namespace list getFixedT resolves it with), so t keeps its identity as long as the resolved prefix does, just like a string keyPrefix. A selector that resolves to a different key still gets a new t, and i18next still resolves the selector on each t call as before. Fixes #1936.
• fix: useTranslation kept returning the previous t when only the namespace (useTranslation('a') → useTranslation('b')) or only the i18n instance (another instance with the same language, via props or I18nextProvider) changed on a mounted component. That t kept resolving against the old namespace or instance until something else (the language, the ready state, a bound i18n event) produced a new one. Both are now part of the check that decides whether the cached t can be reused.

17.0.18

• fix(Trans): with shouldUnescape, the default unescape now turns   and &[#160](https://github.com/i18next/react-i18next/issues/160); into a no-break space (U+00A0) instead of a regular space (U+0020). The regular space dropped what the entity is for: u nás or 10 km could wrap across lines, and consecutive  s collapsed into one space. This also matches IcuTrans, whose entity decoder already mapped   to U+00A0. Compatibility note: only affects shouldUnescape; snapshots or exact textContent comparisons of such text now contain U+00A0 (Testing Library's default normalizer still matches it as a space). A custom react.unescape function can restore the old mapping for text nodes. Thanks @​lprnmns (#1935).

17.0.17

• perf: useTranslation no longer unsubscribes and resubscribes its i18n listeners on every render. The subscribe callback handed to useSyncExternalStore depended on the merged options object, which is rebuilt whenever props is a new object: with no options (the {} default), with options passed inline (useTranslation('ns', { keyPrefix })), and through withTranslation and <Translation>. A new subscribe makes React resubscribe, so each render of each caller ran i18n.off and i18n.on in an extra effect. It now depends only on the instance and the bindI18n/bindI18nStore event names. No updates were ever missed, because React re-checks the snapshot after resubscribing; this only removes the churn, which adds up with many mounted components that re-render often. Reported via next-i18next#2349.
