[infra] More frequent dev releases

[dcharkes]

Would it be possible to have more frequent dev builds?

Currently have a dev tag every 4 hours if I'm not mistaken.
But a dev build only goes out 2 times (?) a week.

For bugs only showing up from a published SDK (for example #56080), it could be helpful if we had more dev builds.

If there is a good reason why we don't do more dev releases, please feel free to close this issue.

Summary: The user requests more frequent dev builds to help debug issues that only appear in published SDKs. They suggest increasing the frequency from the current twice-a-week schedule.
