Bump undici sub-dependency from v5.5.1 to v5.8.2

[watson]

Note to reviewers

Before adding the commit 9fa9227 and f55c5a0 to this PR, a lot of the tests failed with this error message:

ReferenceError: AbortSignal is not defined
  at Object.<anonymous> (node_modules/undici/lib/fetch/request.js:839:3)
  at Object.<anonymous> (node_modules/undici/index.js:99:28)

I boiled it down to this combo:

• Running jest pre v27
• Having testEnvironment: 'node' in the jest config
• Referencing the AbortSignal object somewhere in the test path

If you remove testEnvironment: 'node' (as I do in 9fa9227 and f55c5a0) or upgrade to jest v27 or newer (see jestjs/jest#11182), the error goes away.

However, when trying to replicate this issue in an isolated environment I was not able to make the issue go away by simply removing testEnvironment: 'node'. So there's something in our particular jest config that somehow avoids this problem when testEnvironment is not set (but we're not alone). So while the default of testEnvironment is node according to the docs and so removing this line shouldn't make a difference, our setup might so different from a regular setup that there's unforeseen side effects by removing testEnvironment: 'node'. So upgrading to jest v27 or newer is probably the best thing to do.

No need to backport to 7.17 as undici isn't used there.
