AbortController is not defined

[Neurone]

Describe the bug
Running the test suite you get tons of errors like:

Retrying request... ReferenceError: AbortController is not defined
    at /home/developer/workspace/extension/packages/background/src/utils/http.ts:2:2937

AbortController was introduced since NodeJS 15, but the required NodeJS version in .npmrc is 14.17.6. I suggest to upgrade to a newer version. I.e., I tried the test suite with NodeJS 16 and everything looks fine.

To Reproduce
Steps to reproduce the behavior:

1. Clone the repo
2. make install
3. make build
4. make test
5. See errors

Expected behavior
Test suite runs without errors.
