Fix the licence check name in report-diff-fields.json

report-diff-fields.json addresses the licence row as
/checks/[name=License summary]/report/licenses, but dtq-dev-9-base ships
that check as "License":

  dspace/config/modules/healthcheck.cfg
    healthcheck.checks = General Information, Checksum, Item summary,
                         User summary, Log Analyser Check, License, Embargo info
    plugin.named.org.dspace.health.Check =
      org.dspace.health.LicenseCheck = License

ReportDiff resolves a [name=...] segment against the check name recorded in
the stored report, so the mapping can never match and report-diff silently
drops the licences row from both the field mapping and the field order.
"License summary" is the name healthcheck.cfg uses on dtq-dev, which is
where this resource came from; HealthReportIT on this branch already
addresses the same check as "License".

healthcheck.cfg is deliberately not touched: the shipped check names are
correct, the resource was the outlier.
