refactor(Dockerfile): use latest stable chrome with matching driver

[rubda]

Pinning google-chrome-stable is not the easiest as versions are removed from time to time as the newer versions usually become the stable ones.

I've seen efforts in bumping the Chrome versions manually a couple of times:

• https://github.com/algolia/docsearch-scraper/commit/1169b0b8d926ed098026f01ccccae6423607d8d9#diff-3bb4f830690e6edb8b6b97c62ef18eae8af2a6b1c5aeb08aaf921c2a22692ef7
• https://github.com/algolia/docsearch-scraper/commit/d8e72b812ea418e99671bebd5a9d454e003d161e#diff-3bb4f830690e6edb8b6b97c62ef18eae8af2a6b1c5aeb08aaf921c2a22692ef7
• ...

So in order to avoid issues like this in the future, always install the latest stable version of Google Chrome as well as the matching ChromeDriver according to their own documentation.
