test(manifest): parse changelog version with Select-String instead of foreach

Replace the foreach-over-Get-Content changelog-version parse with Select-String,
which returns the first matching line's named capture group directly — no loop and
no break. The foreach existed only to avoid the canonical template's unreliable
`ForEach-Object { ... break }`; Select-String removes the need for either form.
Mirrors the upstream fix in tablackburn/PowerShellModuleTemplate#37.

Build + Pester pass locally: 786 passed, 0 failed, 23 skipped.
