[haskell-servant][haskell-yesod] Use table-based conversion for field name conversion (#16232)

* [haskell-servant][haskell-yesod] use table-based conversion for field name conversion

name, but it is inappropriate if the original JSON field name begins
with a capital letter.

* [haskell-servant][haskell-yesod] regenerate samples
