Remove the limit of unnamed template argument number

[xxyzz]

0 and above 1000 are allowed in MediaWiki, for example, fr edition's "cardinaux/vi" template:

Those are some big numbers. This seems obviously correct to me, and if the numbers go that high I bet the limit is actually something like int, in which case it doesn't really make sense to check upper limits.

However, we might need to check for lower, so there should still be a k < 1 test. In that case you might as well leave the deleted block and replace the magic number 1000 with MAX_TEMPLATE_KEY_VALUE_INT or something similar, and make the constant the size of an unsigned(?) int or whatever makes most sense... If there is anything that makes the most sense. PHP doesn't seem to have unsigned ints, but it does have different sizes for 32 and 64 bit... Yeah, I guess at this point it doesn't make sense to check max, just k < 1.

0 is also allowed and str.isdigit() returns False for negative string number so I think we don't need more checks.

Then everything seems correct.
