docs(servers): fix mutation-comment caller branch label (#1359)

The previous comment named the GET handler's "seed branch" as a caller
of normalizeMcpServers, but that branch returns DEFAULT_SEED_CONFIG
directly without normalizing. The actual second caller is the
file-present branch (after parseStore). Correcting the label so a
future reader looking for the seed branch caller doesn't waste time.
