Omit webdrivers gem from Gemfile template

As of Selenium 4.6, [the Selenium Manager is capable of managing Chrome
Driver installations and integrations][readme]. As of Selenium 4.11, the
Selenium Manager is capable of [capable of resolving the Chrome for
Testing installation][] path.

By omitting the `gem` declaration from the `Gemfile.tt`, newly generated
applications and applications updating their `Gemfile` in lockstep with
newer Rails versions can shed the dependency and avoid test failures
introduced by newly released Chrome versions (like, for example,
[titusfortner/webdrivers#247][]).
