--- Builtin diagnostic
---
--- Highlight lines with matches of current diagnostic items. Items are computed
--- with |vim.diagnostic.get()| for current (source) buffer.
---
--- It prompts integration highlighting update on every |DiagnosticChanged| event.
--- Diagnostic items with higher severity (see |vim.diagnostic.severity|) have
--- higher highlight priority (errors will be shown over all others, etc.).
---
---@param hl_groups table|nil Table defining highlight groups. Supplied fields
--- also define which diagnostic severity to highlight.
--- Can have the following fields:
--- - <error> - highlight group for error items.
--- Default: |hl-DiagnosticFloatingError|.
--- - <warn> - highlight group for warning items. Default: `nil` (not shown).
--- - <info> - highlight group for info items. Default: `nil` (not shown).
--- - <hint> - highlight group for hint items. Default: `nil` (not shown).
