Review Comment:
   Sorry, I misread this the first time round: you meant an `# Errors` section, 
not just dropping `# Panics`. Done in 65621ddaa, for every `try_` function this 
PR touches:
   
   * `FFI_ArrowSchema::try_new` had the reason in prose, it now has an `# 
Errors` section
   * `try_binary` said `# Error`, now `# Errors`
   * `try_from_trusted_len_iter` did not say what its `Err` meant at all
   
   Left alone, to keep the diff to what this PR is about: the pre-existing 
`try_` functions in the same files that also lack `# Errors` (`try_unary`, 
`try_unary_mut`, `try_binary_mut`, and the eight `MutableBuffer::try_*` from 
#10317). Happy to sweep those too, here or in a follow-up, whichever you prefer.
