Wrong HTTP status for HEAD request

Hi,

In Solr 8.6.1, a GET request or a HEAD request for a non-existing term in a
managed resource (stopword or synonym) returns a HTTP status "404 Not
Found".

$ curl -i "
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar"
| head -n 1
HTTP/1.1 404 Not Found

$ curl -I "
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar"
| head -n 1
HTTP/1.1 404 Not Found

In Solr 8.7.0, the same GET request still returns "404 Not Found", but the
HEAD request now returns "200 OK" as if the term actually exists.

$ curl -i "
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar"
| head -n 1
HTTP/1.1 404 Not Found

$ curl -I "
http://localhost:8983/solr/techproducts/schema/analysis/synonyms/english/foobar"
| head -n 1
HTTP/1.1 200 OK

I presume that's a bug?

Thomas
