Missing FOND PDDL requirement in syntax highlighting

[Frederico-Messa]

I noticed that the extension unfortunately does not support FOND Planning¹ domains at the moment. I was wondering whether there is an easy way to make this improvement. At the moment the keyword :non-deterministic is not yet supported. I think it should be added here and here. The single additional operator oneof should also be added.

Thanks in advance!

I think the oneof operator would be added to here such as by

        this.addSuggestionDocumentation('oneof', 'Nondeterministic effect',
            new MarkdownString('Nondeterministic choose one of effects to handle. For example:')
                .appendCodeblock('(oneof (and (at ?to_location) (not (at ?from_location))) (and ))', PDDL)
                .appendMarkdown(discreteEffectHint)
                .appendMarkdown(requires([':non-deterministic'])), CompletionItemKind.Method);

I can set up a pull-request to add this and also Frederico's suggestions if that is all is needed?
