fix(lsp): resize hover window for concealed lines

Browse Source 
Problem:  Height of a (markdown) `vim.lsp.util.open_floating_preview()`
          window can be reduced to account for concealed lines (after #31324).
Solution: Set the window height to the text height of the preview window.
          Set 'concealcursor' to avoid unconcealing the cursorline when
          entering the hover window.
