Text in getting_started/counters.mdx doesn't match the code

[fhars]

The description for counter_component says "for that, we use ()", which is actually never used in the code snippet, and if you try to "Notice the module inclusion via module Model = Model" in add_counter_component, you will mostly notice its absence.

Both seem to have been removed with https://github.com/janestreet/bonsai/commit/227499d537f33696bfa4371f9162ca9eba7f0f5f

I believe this has now been fixed internally. The fix will land on the main branch soon.
