codeintel: Return resolved rev from CommitDate
Created by: efritz
This PR additionally returns the resolved rev from the revlike given to CommitDate
in the gitserver client layer.
See enterprise/internal/codeintel/policies/matcher.go for the significant difference: we want to return commit
instead of policy.Pattern
when previewing the configuration policy in the UI. Before, we would see the preview for any input be input <badged>input</badged>
, where now we will see resolved-rev <badged>input</badged>
, as expected.
