test(argocd): fix FallbackToAnySHA test to use a host not in the known-hosts list

gitea.internal.corp contains 'gitea.' which matches the known git host
heuristic, so the test was actually hitting Pass 1, not the fallback.
Replace with git.acme-corp.internal which has no known-host prefix,
no chart-registry prefix, and no .git suffix, so resolveMultiSourceRevision
genuinely falls through to the SHA-shape fallback (Pass 2).
