fix: remove parse_trans from runtime dependencies (#714) (#806)

parse_trans provides ct_expand which is only used at compile time for
evaluating cipher suites and decoding CA certificates. The results are
baked into the .beam files at compile time, so parse_trans is not
needed at runtime.

This reduces the runtime dependency chain, particularly helping users
with environments that don't include syntax_tools (like elixir-desktop).
