docs: fix incorrect code examples in Reply and Request reference (#6582)

Mahmoud Hamdy · web-flow · commit a1413de2033b · 2026-03-16T00:50:27.000-07:00
- Replace non-existent `reply.getTrailer()` with `reply.hasTrailer()`
  in the removeTrailer example
- Fix syntax errors in schema mutation examples where an extra dot
  before the assignment operator made the code invalid
  (`schema1.properties.foo.type. = 'integer'`)
