fix(ubuntu-universe): fix two ARM64 bugs in ports repo state

[jonathanlooi]

Problems

Bug 1 — hardcoded Suites: noble
The ubuntu-ports repository entry was hardcoded to noble, meaning the
state only works on Ubuntu 24.04. On Ubuntu 22.04 (Jammy), universe packages
couldn't be resolved, causing multiple SIFT tools to fail to install.

Bug 2 — YAML rendering failure in unless clause
The list form of unless with a grep command containing URIs: http://...
causes Salt's YAML renderer to misparse the colon-space as a mapping key,
producing a CRITICAL rendering error that skips the entire state:
[CRITICAL] Rendering SLS 'base:sift.repos.ubuntu-universe' failed: could not find
expected ':'

Fixes

• Replace Suites: noble with the lsb_distrib_codename grain so the correct suite
  names are used for any supported Ubuntu release
• Flatten the unless list into a scalar with a simplified grep pattern, avoiding
  the YAML parsing conflict

Tested on

• Ubuntu 22.04 LTS ARM64 running in UTM on Apple Silicon (M-series Mac)

This was addressed in another PR. Appreciate you opening this up though.
