Selenium 4.45 Released

[Java] New support for driving Electron apps via ElectronOptions/ElectronDriver, plus a published selenium-devtools-latest artifact.
Cross-binding Continued migration of shared “atoms” (isDisplayed, getAttribute, find-elements) from Closure to TypeScript, now adopted across JavaScript, Ruby, Java, and .NET.
[Grid] Hardened the WebSocket proxy (pre-handshake race, TCP backpressure, fast-path framing) and added Redis-backed SessionQueue support alongside the already-bundled Redis SessionMap.
[Python] New high-level BiDi network APIs for request/response/auth handling and extra headers, plus BiDi script module alignment with the cross-binding API design.
[Ruby] Deprecated the curb HTTP client and Chromium Profile classes, and split responsibilities between Service, DriverFinder, and Options.

[Build] Broad CI/release modernization: Bazel bumped to 9.1 and a rerun-safe release pipeline.
