[SchemaRegistry] Fix broken test recordings (#14935)

* Update tests to use single-line strings. Recording encoding was keeping the /r/n from Windows and breaking everything.

* Ignoring tests since I cannot figure out the encoding issue.

* Added missing readme sections.

* Ignored the other tests as they suffer from the same issue.

* Fix readme link.

* Really... it needs to say that exact phrase.
