Sensitive Data Exposure (CWE-532): Insertion of Sensitive Information into Log File

Correct the token-handling comments.

--skip-redaction disables Buildkite log redaction for this lookup, so line 44 must state that exception. BK_TOKEN is used by the shell curl Authorization header; .buildkite/scripts/crcr_report.py receives OIDC_TOKEN, not BK_TOKEN. Do not claim that BK_TOKEN cannot reach logs unless callers also prevent shell tracing, which exposes command-substitution assignments and expanded arguments.

In @.buildkite/scripts/crcr-report.sh at line 44, Update the token-handling
comments near the redaction note to accurately state that --skip-redaction
disables Buildkite log redaction for this lookup, BK_TOKEN is used in the shell
curl Authorization header, and crcr_report.py receives OIDC_TOKEN rather than
BK_TOKEN; remove any claim that BK_TOKEN cannot reach logs unless shell tracing
is also prevented.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli.

# Deliberately not passing --skip-redaction. On the deployed agent
# (v3.73.1) the flag cannot help: secret_get.go creates the Job API
# client unconditionally and only checks SkipRedaction afterwards, so
# under the docker plugin -- which does not expose the Job API socket to
# the container -- it fails before the flag is read. That ordering was
# only fixed in v3.107.0. Skipping redaction would also stop the token
# being registered with the log redactor, for no gain here.
