fix(tools/looker): log request/response traces at debug, not error

The looker-get-dashboards and looker-generate-embed-url tools logged their
"Making request"/"Got response" traces with logger.ErrorContext, while every
other Looker tool logs the same traces with logger.DebugContext. Because
StdLogger routes Error to stderr, these routine, successful traces surfaced as
ERROR-severity stderr lines on every call at the default log level: log spam
and false positives for log-based alerting.

Switch the four calls to DebugContext so they match the package convention and
are suppressed at the default log level. Message strings are unchanged.
