ci: Separate test dependencies into dedicated workflow job (#102)

Split the update-deps workflow into two jobs:
- update-deps: Handles production dependencies (Dotnet SDK)
- test-deps: Manages PowerShell test version dependencies

This separation allows test dependencies to skip changelog entries
while production dependencies continue to be documented. The test
versions are infrastructure changes rather than user-facing updates.

Also removes the PowerShell v7.4.12 changelog entry since test
dependency updates will no longer generate changelog entries.
