Move to Bencher CLI GitHub Action

[epompeii]

Move Bencher in CI over to the Bencher CLI GitHub Action.

Also add a Bencher perf image to the readme to illustrate the similarities in performance for log4rs vs trace4rs.

Is BENCHER_API_TOKEN still set as a repository secret?

I sanity checked by running a nearly identical test on my own repo and things worked:

• bencherdev/bencher@30dd1d4
• https://github.com/bencherdev/bencher/actions/runs/4460440610/jobs/7833580893

And on the PR branch as well:

• https://github.com/epompeii/trace4rs/actions/runs/4469180005

I also checked the API token locally, and it is still valid and working.

I believe what is happening is because I don't have the appropriate permissions on the repository GitHub is not actually providing the secret. This is in order to prevent randos from being able to leak/exfiltrate repository secrets.

error: a value is required for '--token <TOKEN>' but none was supplied

I'll take a look at the settings and send you a message.

It appears that I do not have access to that. We'll need to talk to someone about getting access to that.
