fix(shard-admin): say the pending unlink will be retried, not that it was

"Still linked on the shard" said "tried 1 time, and tried again when the
bridge reconnects" about a retry that has not happened yet. It now reads
"tried 1 time. It tries again when the bridge reconnects." Found in the
account deletion walk (docs/website/ACCOUNT_DELETION.md step 6, W2).
