Remove unneeded "eslint-disable no-restricted-properties" from several files

Remove unneeded "eslint-disable no-restricted-properties" from several files

This was added in 160fc196fe43300843cc6cb68ad912051b7fb1d9 to suppress
warnings about usage of jQuery utility methods.

In eslint-config-wikimedia v0.9.0, the jQuery utility methods got its
own warning code, and change 3e4e0a5774cb7531c8be7516e57550477489753d
updated all files that use them to suppress each individual warning,
but did not remove this now-unnecessary global suppression.

Currently (since 6ad73362f376a0399bd1568fe7bbf40425737311), these
comments are instead incorrectly suppressing warnings about usage of
JavaScript methods introduced in ES6 and later.
