ci: Switch iroha2 default image to debian-based

[BAStos525]

Solution

1. Use Debian based image by default for iroha2 image.
2. Set the default retention policy for executor.wasm artifact as we need it to be able to be downloaded.
3. Enable checkout branch/commit option for all custom images build & push job.

Close #5100

Note

Building iroha based on glibc and Debian increases compilation time in aboit two times. iroha based on glibc and Debian increases image size in about three times.
