fix(ci): interop test parallelism (#8674)

* fix(ci): interop test parallelism

It broke when require got replaced with modern import statement,
and CI run all tests four times.. every time.

* fix(ci): run interop with 2 vCPUs

We often have 3 processes (tests and 2 or more IPFS nodes)

* fix(ci): cache npm during interop

* fix(ci): run interop on 2xlarge

It is similar load as sharness, so let's use same beefy box

* fix(ci): enable ipfs-webui

it was skipping due to missing chromium binary

* fix(ci): force fresh npm cache during interop

Needed to pull-in @chainsafe/libp2p-noise@5.0.2
