Resolve `chromedriver` issue via CircleCI config and dependency adjustments

Summary

Upgrade of `browser-tools` in CircleCI config:

By upgrading the browser-tools Orb to version 1.4.6 in our CircleCI configuration, we fix this issue when installing Chromedriver:

Installed version of Google Chrome is 116.0.5845.140 
curl: (22) The requested URL returned error: 404

Exited with code exit status 22

Issue: Installed version of Google Chrome is 116.0.5845.140 causing a 404 error

Removal of `webdrivers` gem:

Since selenium-webdriver already inherently includes webdrivers as a dependency, explicitly requiring it proved to be unnecessary and was causing version conflicts.

Webdrivers::VersionError:
  Unable to find the latest point release version for 116.0.5845.
  You appear to be using a non-production version of Chrome.
  Please set `Webdrivers::Chromedriver.required_version = <desired driver version>` to a known chromedriver version: https://chromedriver.storage.googleapis.com/index.html

Issue: Webdrivers trying to load a Chrome version that doesn't exist
