Refreshed images

[ctron]

Checklist

• I've looked through the issues and pull requests for similar request
• This feature could be solved with a custom image (optional)

Describe your request

Right now, container images are based on Ubuntu 20.04 (after that was 22.04, now there is 24.04). There's a centos 7 images (after that came 8 and 9, now 10).

I think it is time to refresh those images. Or at least, provide newer variants.

Describe why this would be a good inclusion for cross

The reason for having those is because some -sys crates seem to struggle with older versions. openssl-sys seems to have issues (missing some features) due to the old libssl present in the 20.04 version.

this is planned for 0.4.0
