[💡 Feature]: Add certificate to Browserstack service config

[th0car]

Is your feature request related to a problem?

Users running WDIO and @wdio/browserstack-service using a corporate proxy requiring root certificate are unable to add this config in wdio.conf.js browserstack service section.

Describe the solution you'd like.

Add configuration corresponding to the Browserstack Local Binary CLI flag --use-ca-certificate to the opts property for browserstack service and apply it when executing binary along with already existing config options like proxyHost and ProxyPort.

Describe alternatives you've considered.

Local binary can be started manually in terminal with the cert as argument for --use-ca-certificate but this is a bad workaround at its best.
