ci: run browser tests without circle

[dyladan]

The circle ci image we've been using for testing was causing permissions issues in github actions. This was the original reason for the permission setting in the action run. Chrome has since been added to the default runner so we actually don't need the image at all.

Seems like karma has some problems with node v18: https://github.com/open-telemetry/opentelemetry-js/actions/runs/3243835797/jobs/5319134741

https://stackoverflow.com/questions/69692842/error-message-error0308010cdigital-envelope-routinesunsupported maybe we need to downgrade to Node.js v16 instead.
