fix: upgrade prop-types dependency to 15.6+

[adamstankiewicz]

Summary

We ran into an issue using react-instantsearch-dom@latest during local development with regard to the prop-types@15.5.10 package, which seems to cause the following runtime error:

Uncaught TypeError: prop_types__WEBPACK_IMPORTED_MODULE_10___default.a.exact is not a function

It looks like the exact function was not added until prop-types@15.6.0 according to the CHANGELOG, but the SearchBox component of react-instantsearch-dom makes use of PropTypes.exact while remaining on prop-types@15.5.10.

This manifests as a runtime error during local development when using react-instantsearch-dom as seen above.

Result

By upgrading the prop-types package to v15.6+ (opting for prop-types@latest here), this error should no longer happen when we are trying to use react-instantsearch-dom during local development.

thanks for finding this! We must have missed it due to dependency deduplication and other dependencies using a new enough version of prop-types that it didn't cause an issue

this has been released as 6.8.3 now, thanks @adamstankiewicz
