5.5 Installer Makefile: Fails with dependency on removed file, schema_dv_mdb_copies.xml

[kcondon]

The 5.5 make file fails with this error:
copying jhove schema file
/bin/cp ../../conf/jhove/jhoveConfig.xsd dvinstall
make: *** No rule to make target ../../conf/solr/8.8.1/schema_dv_mdb_copies.xml', needed by dvinstall/schema.xml'. Stop.

This is apparently due to a dependency on the recently removed schema_dv_mdb_copies.xml, see #7865 . This was manually fixed by temporarily adding back the file to produce the 5.5 dvinstall.zip but the dependency needs to be fixed/removed.

Less critical but on topic is that schema_dv_mdb_copies.xml also appears in the dev guide and the curl command highlighted in blue below from https://guides.dataverse.org/en/5.5/developers/dev-environment.html#install-solr will fail.

We might as well fix both in the same pull request, I'm thinking.
