[Suggestion]: generalize ; for argument delimiter

[boltlessengineer]

In #39, we discussed about using ; as an attribute delimiting modifier.

We can generalize this for other argument-style grammars.
Currently one I can think of is macro arguments:

.image path/to/image.png; more; arguments

@code bash; nonumber
@end

There was a suggestion to separate attributes and macros (#38), and I don’t think having similar syntax for arguments will make user confused as long as we use different prefixes.

We can also adopt this to norg-meta grammar:

categories: [cool project idea; neovim]

Now ; is used to separate multiple inline elements in all Norg syntax. Making general Norg syntax more consistent.

• attributes (for both detached/attached modifiers)
• macro parameters
• arrays in norg-meta
