Dependency updates, bump jest maxWorkers to 3

[askoufis]

• Removed babel-plugin-dynamic-import-node. This plugin was only being used in jest, i.e. Node, but dynamic import has been supported in Node since 13.2.0, so there's no need to transform it anymore.
• Updated less-loader version, primarily to prevent consumers getting locked to a version without this fix that removed an unused, very old dependency that ended up including various old versions of things, as well as node-gyp in node_modules 🙅
• Updated node-emoji to the latest major version. Was waiting for them to release my change.
• Set maxWorkers to 3 on CI as the macos github agents have 3 cores, so we might as well use them. Looks like we can get <5 minute test runs on CI pretty consistently now. This will go away if we eventually move back to ubuntu images, but it's nice to have for now.

Not a huge issue, but I would mark these changes as minor. I would say the removal of code falls in the same category as adding code.

Determining whether the change is a patch level or minor level modification depends on whether you updated your dependencies in order to fix a bug or introduce new functionality. We would usually expect additional code for the latter instance, in which case it’s obviously a minor level increment.

I'm not too fussed about the semantics, though. Feel free to leave it as is if you disagree.

Split out the changeset into two separate ones: one for dep updates, and the other for the dep removal. Also snuck in a node-emoji update too since they finally released a new version.
