chore(deps): bump sinon to 22.1.0 in every package
Because: - FxA packages resolved four sinon versions, from 4.5.0 to 15.2.0. This commit: - Sets sinon ^22.1.0 and @types/sinon ^22.0.0 in every package that uses them. - Migrates content-server tests to createSandbox and calledWithMatch. - Imports fakeServer from nise, which sinon 22 no longer bundles. - Points the content-server webpack alias at the sinon ESM bundle. Closes FXA-2961
