Linus Groh 0974991d05 LibJS: Don't treat '?.' followed by decimal digit as QuestionMarkPeriod ...

From the spec: https://tc39.es/ecma262/#sec-punctuators

    OptionalChainingPunctuator ::
        ?. [lookahead ∉ DecimalDigit]

We were missing the lookahead and therefore incorrectly treating any
'?.' as TokenType::QuestionMarkPeriod.

Fixes #4409.
