Description

Follow-up to #14767. This trims the comments and two docstrings in the Cloud Scheduler samples so that each comment states one fact a reader needs. The code doesn't change.

• Multi-line comments are now one line, for example the schedule and time zone, the attempt deadline, the retry limits and backoff, and the ABORTED behavior on pause, resume, and update.
• Removed comments that restated the code, such as list pagination and the App Engine deadline.
• Shortened the create_job and cloudscheduler_receiver docstrings.

11 files changed, net 37 fewer lines.

Checklist

Testing

Compliance & Style

• The README is updated with all relevant information (if applicable). Not applicable.
• If this PR adds a new sample directory: I updated the CODEOWNERS file. Not applicable.
