## Description
This PR does a few minor improvements to the formatting of the benchmark results:
- changes the title from `<h1>` to `<h2>`, consistent with other hasura-bot reports AFAICT
- concatenates lines together to allow for more natural line wrapping
- allows for the detailed report to be collapsed (but is open by default)
## Notes
The state of the report (open / closed) isn't persisted across refreshes, and I don't know if it's feasible for it to be. An alternative would be to, when generating a new report, edit the old ones to make them collapsed by default.
