This version of the JSDoc plugin [switches the mode to `typescript` by default](https://github.com/gajus/eslint-plugin-jsdoc/pull/1063). Without it, we have to enable this mode manually, as in [this PR](https://github.com/MetaMask/metamask-module-template/pull/220/files#diff-e2954b558f2aa82baff0e30964490d12942e0e251c1aa56c3294de6ec67b7cf5).
