[CI] Mirror api.github.com using scheduled job (part of #11672)

[bonigarcia]

Description

This PR includes a new job in CI for mirroring and filtering the responses of api.github.com for discovering the Selenium releases programmatically. The mirror is required to avoid the error HTTP 403 get requesting the GH API. This error is well known from WebDriverManager (see job).

Motivation and Context

This PR is the first step for implementing #11672. The second step is to implement the Rust code to read the resulting mirror.
