Correct vue.config.js example

[lindsaykwardell]

A bracket is missing from the vue.config.js configuration example, this change would add in the missing bracket so the code example is valid.

Description of Problem

In the code example for vue.config.js to add the compat rule, a bracket is missing which results in an error when copy/pasted.

Proposed Solution

The proposed solution would be to add in the bracket, so that the code example is correct and valid.

Looks good. Thanks for the fix.

I just attempted to submit this same fix before finding that this had already been fixed ~6 weeks ago. Apparently the deployed version has not been updated in that time, because it still has this syntax error.

@catrope The docs deploy automatically when changes are merged. Perhaps you're seeing a cached version? The 'Last updated' time at the bottom of that page should read '2021-07-13, 16:56:51 UTC'.

I guess I must have seen a cached version somehow. I just opened the same page again and it looks right this time.
