Update params.md

correcting a typo in line 184 which previously read "This can leads to bugs". Now it reads "This can lead to bugs". Removed the 's' in lead. (under version 5.x)

READ ME PLEASE!

TL;DR: Make sure to add your changes to versioned docs

Thanks for opening a PR!

The docs cover several versions of react-navigation, and in some cases there are several files (for version 1, version 2 and etc.) that all describe a single page of the docs (eg. "Getting Started").

Please make sure that the edit you're making in docs/file-you-edited.md is also included in the file for the correct version, eg. /versioned_docs/version-3.x/file-you-edited.md for version 3. If such file doesn't exist, please create it. :+1:
