Add a rspec lint check to check title: and description:line lengths.

• Initial the maximum title: line length will be 154.
• Initial the maximum description: line length will be 80.
• Initial start date is May 9, 2026 and it is the earliest start date with no failed checks.
• Also excluded OSVDB advisory since they are very old.

These max numbers are at or close to the minimum to get a clean "rake" run.
