UnusedImport warning is displayed for every runnable example

[Jjp137]

For every usage of runnableExamples within a module, an UnusedImport warning appears
when documentation is generated for that module, and the warnings occur in a file that nim doc itself generates.

For large modules with many documented procs and runnable examples, this can result in dozens of false warnings from the user's perspective.

Example

## An example module.

proc addOne*(x: int): int =
  ## Adds one to an integer and returns the result.
  runnableExamples:
    doAssert addOne(1) == 2
  result = x + 1

Generate the documentation with nim doc.

Current Output

Within the usual compiler output:

/home/jjp/.cache/nim/example_d/runnableExamples/example_examples.nim(1, 8) Warning: imported and not used: 'example_examples1' [UnusedImport]

Expected Output

The UnusedImport warning should not appear.

Possible Solution

Would disabling that warning via a pragma at the top of the generated file (in this case, example_examples.nim) work? Or are there better solutions?

Yeah and it's the right way to do it.
