fix: "infinte" typo

[evils]

the documentation generated from this file has inf on this line as **inf**, i don't know what caused that markup to be applied and cannot be sure it will still be after this change

side note: i assume this refers to either positive or negative infinity, would it be useful to state that?
though looking a bit closer (i'm not familiar with the language this is written in), it seems to be of type duration, rather than a float, as stated by the comment, maybe someone can clarify?
