wasmer tests hanging in CI

[ascorbic]

The WInterJS/wasmer tests are mostly hanging in CI, causing the support updates to fail. For this reason I've disabled the tests for now. It can be intermittently reproduced locally when running pnpm generate in the root. It doesn't seem to happen so much when running the tests on their own in the generator/runtimes/wasmer directory, and just seems to manifest when run in the group. Setting concurrency to 1 doesn't help.

I will investigate this and report back @ascorbic.
