fix(build): Use public UBI repos to fix build failures

[eranco74]

Walkthrough

The Containerfile modifies the GCC installation step to use dnf with disabled default repos and explicitly enables ubi-9 AppStream and BaseOS repos for installing gcc. No other build steps are changed. A trailing newline was added.

Poem

I nibbled the repos, neat and clean,
Enabled two, the rest unseen.
GCC hops from UBI’s fields,
Predictable roots, consistent yields.
A newline wink at file’s tail end—
Ship it swift, your container friend. 🐇✨
