bootstrap: still require COMPILETEST_FORCE_STAGE0 for ./x test rustdoc-js --stage 0

[jieyouxu]

This PR reverts #135375, because through some more testing I found out ./x test rustdoc-js --stage 0 does not in fact build rustdoc, and all the tests fail. This can't be intended behavior, so at least require COMPILETEST_FORCE_STAGE0 to make it less likely to run rustdoc-js --stage 0 by accident.

The problem that --stage 0 is not working at all for this rustdoc-js test suite is tracked over at #135603.
