don't wrap last array item when trailingComma is 'none'

[artembelik]

Hi, thanks for the awesome plugin, but I noticed a strange behavior when trailingComma is 'none'

.prettierrc

{
    printWidth: 120,
    tabWidth: 4,
    useTabs: false,
    singleQuote: true,
    trailingComma: 'none', // <---
    plugins: ['prettier-plugin-multiline-arrays'],
}

source:

const { join } = require('path');

const arr = [
    join('...', '...'),
    join('...', '...')
]; // <---

after prettier --write:

const { join } = require('path');

const arr = [
    join('...', '...'),
    join('...', '...')]; // <---

Nice catch! I'll try to repro and fix.

Note: this also happens in JSON (since JSON doesn't allow trailing commas)

I have the same issue with trailingComma: 'es5'

Original code

{
    "files": [],
    "references": [
        {"path": "./tsconfig.app.json"},
        {"path": "./tsconfig.node.json"}
    ]
}

after this plugin is executed, I ended up with

{
    "files": [],
    "references": [
        {"path": "./tsconfig.app.json"},
        {"path": "./tsconfig.node.json"}]
}
