Update deposit metadata so it's not rejected by the deposit >= v2.0

New version 2.0 added some more functional checks on the metadata. The icinga checks triggered by the infra is now being rejecting by the deposit.

So the jesuisgpl.tgz.xml needs some metadata updates to pass that check.

Deposit was rejected: 
- client is not a valid Atom element, see https://datatracker.ietf.org/doc/html/rfc4287 (client)
- jobTitle is not a valid Codemeta 2.0 term, see https://github.com/codemeta/codemeta/blob/2.0/codemeta.jsonld (jobTitle)
- Suggested fields are missing (swh:metadata-provenance)
