Remove unused code

[internet-account2]

The removed line isn't used anywhere in this code example or even anywhere in the rest of the page.

It looks like it's copied from https://mdn.github.io/dom-examples/popover-api/toggle-help-ui/ where it was used to hide the help text if no popover support is detected.

Description

Removes unused code from a code example.

Motivation

Reading a code example with irrelevant unused lines is confusing.
