[chore](Regression) Add provider conf in regression's pipeline conf (a…

…pache#36695)

Previously the conf of pipeline doesn't contain the provider of the
Object Storage it uses. When adding azure's support like apache#35990, user
should specify the vendor they use or just doesn't set the "provider"
property when using S3-like object storage. So i add this conf.
