test: blindly attempt to re-enable nightly

[kvakil]

I disabled this in #404. This is a PR so I can futz around with it and try to figure out why the mirror isn't working.

[kvakil]

It fails with this error:

Warning: Unexpected input(s) 'node-mirror', valid inputs are ['always-auth', 'node-version', 'architecture', 'check-latest', 'registry-url', 'scope', 'token', 'cache', 'cache-dependency-path', 'version']
Run No9/setup-node@mirror
Attempting to download 19.x...
Not found in manifest.  Falling back to download directly from Node
Error: Unable to find Node version '19.x' for platform linux and architecture x64.

(The warning probably isn't relevant, I think it just needs this patch:

but I don't think that it's actually causing the issue? actions/runner#514 looks like the upstream issue about the warning.)

@kvakil This is failing because 19.x doesn't exist in https://nodejs.org/dist/
I'll take a look around the issues in core and update here with more info as I find it.

@kvakil So this was easy.
There is no 19.x because it's not due out until Oct 18th nodejs/node#44650
The issue states that latest releases are built against on V8 10.2 same as 18.x so there is not much point using latest in these tests.
From the conversation it looks like there is a workaround to get tier1 support to do a release with v8 10.5 so I would say there will be something in and around the 18th Oct date.
I've put a watch on that issue and we can re-run these tests when that lands.

Now that 19 is released i re-ran the tests
The Ubuntu 18 are failing with:

node: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.28' not found (required by node)
Error: Process completed with exit code 1.

We should probably look at disabling Ubuntu 18 for the 19 tests?
