[REGRESSION]: Snapshot name contains some random string after test name when tests are run in container

[aneeshbaby]

Context:

• GOOD Playwright Version: [1.35.1]
• BAD Playwright Version: [1.36.0]
• Operating System: [Docker Container - Ubuntu 20.4]
• Extra: [We run tests by creating a new container of above Linux flavour and always pick the latest playwright version]

Here is console log of error

Describe the bug

In latest version of Playwright test run in container, it started adding a random string in the file name which in this example is 'a183a6'. This happens only when running the tests in an Ubuntu 20.4 docker container.

We will release a fix as part of 1.36.1
