dapui docs aren't correctly formatted for help syntax

[idbrii]

dapui docs incorrectly use ~ and don't separate arguments (so it blends into a wall of text).

Compare:

                                                                  *dapui.eval()*
`eval`({expr}, {args})

Open a floating window containing the result of evaluting an expression

If no fixed dimensions are given, the window will expand to fit the contents
of the buffer.
Parameters~
{expr?} `(string)` Expression to evaluate. If nil, then in normal more the
current word is used, and in visual mode the currently highlighted text.
{args?} `(dapui.EvalArgs)`

To nvim docs:

nvim_eval({expr})                                                *nvim_eval()*
    Evaluates a Vimscript |expression|. Dicts and Lists are recursively
    expanded.

    On execution error: fails with Vimscript error, updates v:errmsg.

    Parameters: ~
      • {expr}  Vimscript expression string

    Return: ~
        Evaluation result or expanded object

dap's docs also look like nvim's.

Looks like dapui uses scripts/gendocs.lua to convert ldoc to vimhelp. Maybe it'd be better to adapt https://github.com/neovim/neovim/blob/master/src/gen/gen_vimdoc.lua to generate docs consistent with nvim's style.
