Sync with Redot 26.2-stable

* Sync with Redot 26.2-stable

Also removed the CI builds for double precision. We dont distribute binaries for this anyways, and with Godot 4.5 they started including the single precision metadata into the `extension_api.json` which causes failures.

* Fix: Default to single precision in CMake bindings generator when none is specified

* CI: Update Linux runners to `ubuntu-24.04` and adjust artifact naming
