fix: add missing cd commands in 9 ccb_test Dockerfiles

6 code-review Dockerfiles were missing `cd /workspace` between
git clone and git config, causing git config to run from /
(Docker default WORKDIR). 3 perf Dockerfiles were missing
`cd /workspace/original` before git submodule update.

Affected tasks: aspnetcore-code-review-001, calcom-code-review-001,
envoy-code-review-001, ghost-code-review-001, terraform-code-review-001,
vscode-code-review-001, numpy-array-sum-perf-001, sklearn-kmeans-perf-001,
pandas-groupby-perf-001.
