[Regression]: the BiDi test workflow runs the Chrome tests using CDP

[hbenl]

Last Good Version

before #37702

First Bad Version

after #37702

Steps to reproduce

To reproduce locally I used a VS Code debug config that runs the bidi-chromium-* projects and set breakpoints in packages/playwright-core/src/server/chromium/crPage.ts and packages/playwright-core/src/server/bidi/bidiPage.ts. The breakpoint in crPage was hit. When I change the debug config to run the bidi-chrome-* projects, the breakpoint in bidiPage is hit.

Expected behavior

The BiDi test workflow should use the BiDi protocol for Chrome.

Actual behavior

The BiDi test workflow uses the CDP protocol for Chrome.

I think this is the culprit:
