[🚀 Feature]: Download grid within Bindings

### Status
* Ruby: : #12299
* Python: #15666
* Java: (n/a - this can/should be done directly with the remote jar)
* JS:
* .NET:

### Feature and motivation

Ruby has always had a wrapper that will download a specified version of the grid so that it can be started for running tests against the server. This isn't necessary now that we are using bazel for the tests. But. It would be nice to have this for our [example code](https://github.com/SeleniumHQ/seleniumhq.github.io/tree/trunk/examples).
Now that it is [supported by Selenium Manager](https://github.com/SeleniumHQ/selenium/pull/12281), it should be pretty straightforward to support.

### Usage example

This is an example of the Ruby implementation

```
server = Selenium::Server.get(:latest, background: true)
server.start

driver = Selenium::WebDriver.for :remote, url: server.webdriver_url, options: Selenium::WebDriver::Options.chrome

driver.quit
server.stop
```
