Subject: [PATCH] build: replace underscore in Debian version (#10032)

The workflow building Debian packages chokes on branches containing
underscores:

```
{:timestamp=>"2025-04-03T10:31:46.749835+0000", :message=>"Invalid package configuration: The version looks invalid for Debian packages. Debian version field must contain only alphanumerics and . (period), + (plus), - (hyphen) or ~ (tilde). I have '1.29.5~dev.13.ga38df11f~srv_stun' which which isn't valid.", :level=>:error}
```

This replaces the offending `_` with a `~` which should yield a valid
version.
