Describe the issue

highlight.js highlighting of Kotlin number literals doesn't match the actual number literals Kotlin accepts, including false-positives and false-negatives.

Which language seems to have the issue?
kotlin

Are you using highlight or highlightAuto?
No
...

Sample Code to Reproduce

https://jsfiddle.net/u3fn8t9m/

// Correct
val croissants = 34L
val muesli = 34f
val porridge = 34F

// False Negatives
// valid Kotlin - wrong highlighted
val schnitzel = 100u
val hagelslag = 23U
val churros = 99UL

// False Positives
// invalid Kotlin - still highlighted
val muesli = 34l
val melange = 34d
val bagel = 34D

Expected behavior

I expect the highlighting to match the official Kotlin grammar.

Additional context

From the Kotlin Spec section 1.2.3 Literals there are only 3 Rules that define suffixes for number literals:

FloatLiteral:
    DoubleLiteral ('f' |'F')
    | DecDigits ('f' |'F')

UnsignedLiteral
    (IntegerLiteral | HexLiteral | BinLiteral) ('u' |'U') ['L']

LongLiteral
    (IntegerLiteral | HexLiteral | BinLiteral)'L'

However, the current grammar for Kotlin reuses Java numerical parsing which does have significant differences.
