[10b-SDK-2] record the gateway's own spelling of the public route

The SDK coverage matrix (sdks/tests/coverage/build_matrix.py) decides
"implemented" by searching each SDK's source for the gateway's route string,
verbatim and case-sensitive. The gateway declares the public file link as
/{version}/files/public/{PublicId}/{Name*}; this SDK writes {publicId}/{name},
so the endpoint read as missing even though the method is there and tested.

The route is now written out next to the method exactly as the gateway spells
it. That is also the thing a reader wants when checking the two agree
(knowledge.md K23 — an SDK is only covered when its routes are compared
against the gateway's).
