Adjust generated .app file for ra to include seshat as a dep

The quality of auto-detection of properities of a hex dependency was
improved with bzlmod, thus in the MODULE.bazel file, ra is handled
correctly with no hints. In WORKSPACE.bazel/workspace_helpers.bzl,
this not the case, so a full build_file_content is needed.

Bazel 6, due this month, takes bzlmod out of experimental status, so I
don't expect to close up the difference between the systems.

The easier solution is to publish ra to hex.pm with the BUILD.bazel
file included, as it exists in the ra source, and is correct,
eliminating the need for any auto-generation of it when
imported/referenced by rabbitmq-server
