navigator.connection is present in service/web workers.

[mkarolin]

This is a follow up issue for #20122 which removed navigator.connection, but the attribute is still available in workers. Workers should not exhibit a different behavior regarding this attribute.

STR:

1. Start Brave
2. Navigate to the test page https://dev-pages.brave.software/dom-properties/controlled.html created by @pes10k
3. Click Run test

Expected results:
In the connection row values for Service and Web Workers should be null

Actual results:
The values are NetworkInformation (meaning the attribute is available).
