mgr/dashboard: Automatically use correct chromedriver version

Every Chrome version requires a corresponding chromedriver version for the e2e
test to work.
Since we were using a fixed chromedriver version, each time chrome was updated
the e2e scripts stopped working.
With this new script we will check which version of Chrome is installed and
update chromedriver to the correct version.
