unhelpful error message when using [N: int] instead of [N: static[int]] in generic

[ShadowElf37]

This error message is particularly confusing for beginners, who may forget or simply not know to put static. Getting compiler noise makes it impossible to determine what the actual issue is with the code.

Error

fatal.nim(53)            sysFatal
Error: unhandled exception: int128.nim(72, 11) `arg.sdata(2) == 0` out of range [AssertionDefect]

Expected Output

test.nim(4)            test
Error: unhandled exception: Please put static thank you. [AssertionDefect]

Sample Bad Code

type IntArrayContainer[N: int] = object
    arr: array[N, int]

discard IntArrayContainer[3]()

This is an internal assertion failure, which shouldn't occur in the first place, there should be a normal Nim error message instead. So changing the assertion message wouldn't fix the actual issue.
