fix(checkhealth): mitigate issues with duplicate healthchecks #15919

* fix(runtime/health): mitigate issues with duplicate healthchecks
  Previously if a healthcheck was found as Lua and Vim it was executed
  both times.
  This new implementations prefers Lua, therefore if two are found It only
  runs the Lua one, this way a plugin can mantain both implementations the
  Lua one with the method `check()` and the autoload function `#check()`
  (for none HEAD nvim versions).
  **Note: This will require plugins to use `check()` as the function name,
  since the autoload function that wraps the lua implementation won't be
  called**
* docs(health): use spaces and don't overuse backtics

followup to #15259
