[kariharju]

Because we cannot provide any concrete step to the user, better to just log these to the output, so that they do not confuse users. These warnings are:

• CURL_CA_BUNDLE is set
• NODE_EXTRA_CA_CERTS is set
• NODE_OPTIONS is set
• NODE_PATH is set
• NODE_TLS_REJECT_UNAUTHORIZED is set
• PIP_CONFIG_FILE is set
• PLAYWRIGHT_BROWSERS_PATH is set
• PYTHONPATH is set
• REQUESTS_CA_BUNDLE is set
• SSL_CERT_DIR is set
• SSL_CERT_FILE is set
• WDM_SSL_VERIFY is set
• VIRTUAL_ENV is set
