workflow run ls should allow limit=1

[jiparis]

Setting the --limit 1 raises an exception, as minimum value is 2.

✗ cl wf run ls --project myproject --limit 1
WRN API contacted in insecure mode
ERR validation error:
 - pagination.limit: value must be greater than or equal to 2 and less than or equal to 100 [int32.gte_lte]

I believe this is unexpected.
