NcButton missing text/ariaLabel prop in MainMenu causes console warnings

[ishizakahiroshi]

Bug description

After updating to Nextcloud 33.0.3, the browser console shows the following warning on every page load:

[WARN] @nextcloud/vue: You need to fill either the text or the ariaLabel props in the button component.
{uid: 'ishizaka', app: '@nextcloud/vue', level: 1, text: undefined, ariaLabel: null, …}

The warning originates from MainMenu.js calling an NcButton component without providing either a text or ariaLabel prop, which are required for accessibility.

Steps to reproduce

1. Log in to a Nextcloud 33.0.3 instance
2. Open browser developer tools (F12) → Console tab
3. Observe the [WARN] @nextcloud/vue warning on every page load

Console output

MainMenu.js:27 [WARN] @nextcloud/vue: You need to fill either the text or the ariaLabel props in the button component.
    {uid: 'ishizaka', app: '@nextcloud/vue', level: 1, text: undefined, ariaLabel: null, …}
log @ index.mjs:44
warn @ index.mjs:62
render @ NcButton-BaZAY-tN.mjs:236
    @ vue.runtime.esm.js:2700
    @ vue.runtime.esm.js:3891
    @ vue.runtime.esm.js:3462
    @ init.js:85
    @ main.js:22

Expected behavior

The NcButton instance in MainMenu.js should include either a text or ariaLabel prop to satisfy the accessibility requirement enforced by @nextcloud/vue.
