[🚀 Feature]: [dotnet] Rename `WebDriver.dll` to `Selenium.WebDriver.dll`

[nvborisenko]

Description

This is a continuation of #15791 where we raised a topic for confusing project naming.

It would be good to see consistent assembly naming withing package's name:

• WebDriver.dll -> Selenium.WebDriver.dll
• WebDriver.Support.dll -> Selenium.WebDriver.Support.dll

Have you considered any alternatives or workarounds?

It will be a breaking change for all transitive dependencies, the same situation as in #12315. This why it is better to do it in v5.
