fix(fx-core): accept newer 'Can't determine project language' output from func

Azure Functions Core Tools >= 4.0.6280 changed its no-project hint from
'Unable to find project root' to 'Can't determine project language from files'.
Latent assertion in funcTool.it.ts only matched the old text; the env-checker
CI gate (triggered only on deps-checker PRs) caught it. Accept either message.
