CI reliability: experimental tests consistent failure

[legendecas]

node-tests-experimental and browser-tests-experimental consistently fail with following messages:

Error: backwards-compatability/node10/index.ts(1,28): error TS2307: Cannot find module '@opentelemetry/sdk-node' or its corresponding type declarations.
Error: backwards-compatability/node12/index.ts(1,28): error TS2307: Cannot find module '@opentelemetry/sdk-node' or its corresponding type declarations.
Error: backwards-compatability/node8/index.ts(1,28): error TS2307: Cannot find module '@opentelemetry/sdk-node' or its corresponding type declarations.

However, I could not reproduce the problem locally. I believe it is related to b66c650, /cc @dyladan. Retried CI with the full run and it fails consistently.

Hmm. the tests passed for the PR i merged. I wonder if it is related to CI caching. Does changing a package.json file cause a test pass?

[legendecas]

Yeah, touching package.json works https://github.com/open-telemetry/opentelemetry-js/pull/2506/checks?check_run_id=3747563214
