[wasm][test-browser] Add another case for retrying chromedriver launch

In some test runs, launching chromedriver failed
with (dotnet/runtime#44862):

```
Connection refused Connection refused
Connection refused Connection refused
[00:03:37] crit: OpenQA.Selenium.WebDriverException: Cannot start the driver service on http://localhost:37245/
                    at OpenQA.Selenium.DriverService.Start()

                    at OpenQA.Selenium.Chromium.ChromiumDriver..ctor(ChromiumDriverService service, ChromiumOptions options, TimeSpan commandTimeout)
                    at OpenQA.Selenium.Chrome.ChromeDriver..ctor(ChromeDriverService service, ChromeOptions options, TimeSpan commandTimeout)
                    at Microsoft.DotNet.XHarness.CLI.Commands.Wasm.WasmTestBrowserCommand.GetChromeDriver(ILogger logger) in /_/src/Microsoft.DotNet.XHarness.CLI/Commands/WASM/Browser/WasmTestBrowserCommand.cs:line 110

XHarness exit code: 71
```

As a way to handle this, we'll retry if the exception message contains
the string `"Cannot start the driver service"`.
