Update discouraged.md

[pczarn2]

Added int to discouraged functions.

@pczarn2 two things on this:

1) Do you know why Adobe recommends using floor instead of int? It would be useful to know the reason, for example does it support larger numbers than int?

2) The discouraged markdown is generated automatically by adding a discouraged flag on the function or tag, rather than editing this file.

Ah - I see you have done this in #1610

[KamasamaK]

@pczarn2 If you're autogenerating this using /utilities/guide.cfm then this shouldn't require a manual review. I think this is just waiting on #1610.

As a heads up, Lucee already internally just uses Math.floor() for int()

Closing, since the discouraged markdown is generated automatically by adding a discouraged flag on the function or tag, rather than editing this file.
