Tests: Update jQuery Migrate from 3.4.1 to 3.5.2, simplify Migrate setup

Apart from updating jQuery Migrate, the setup is now changed so that exact
Migrate versions are only references when fetching npm packages; other than
that, they're represented as `jquery-migrate-1.x` & `jquery-migrate-3.x`. This
will allow smaller changes when updating jQuery Migrate in the future.

Closes gh-2273
