fix(enterKeyHint): remove check on only Chrome browser

[FabienMotte]

Issue summary

Related issue: #651
Related PR: #916

This issue is still present on Samsung Internet Browser.
This is because this browser is excluded from the isChrome util: https://github.com/algolia/autocomplete/blob/next/packages/autocomplete-core/src/utils/isChrome.ts#L3

Result

Samsung Internet Browser should be detected as Chrome, so enterKeyHint won't be updated and use a fixed value.
