Problem:
I was trying to use playwright-cli in a sandbox as a root user.
playwright-cli open https://www.google.com failed.
Then I tried setting PLAYWRIGHT_MCP_NO_SANDBOX to 1, but it still failed.
After investigating the source code, I found that the env variable has been changed to PLAYWRIGHT_MCP_SANDBOX, and setting this env variable to 0 fixed my problem
playwright cli version: 1.59.0-alpha-1771104257000
