vim-patch:partial:d899e5112079 (#18474)

Update runtime files
d899e51120

- Skip vimhelp.vim stuff (syntax/help.vim, syntax.txt; v8.2.4891).
- Skip :let heredoc eval stuff (eval.txt; v8.2.4770).
- Skip uk.cp1251.po.
- Skip `*hl-CurSearch*` change (syntax.txt):
  - Vim's CurSearch works differently (Nvim's uses current cursor pos).
    Dunno know how applicable the redrawing comment is to Nvim...
  - Might be preferred to move it under `*hl-Search*` like Vim?
