style(@stdlib/plot/components/svg/canvas): fix no-new-array in onRender

The lint workflow (run 26260926243, 2026-05-22) failed on develop with a
`stdlib/no-new-array` violation at line 124 of `canvas/lib/main.js`.
The `onRender` helper pre-allocated an array via `new Array(n)` followed
by index-based assignment before passing it to `self.emit.apply()`. This
constructor form is disallowed by the `stdlib/no-new-array` rule.

Replace the three-step `new Array(n)` + `args[0]='render'` + index loop
with `args = [ 'render' ]` followed by `push()` in the existing loop.
The resulting array is a dense `Array` instance; `Function.prototype.apply`
accepts it identically, so runtime behavior is unchanged.
