When no matching benchmark files are found, a more sensible error is thrown now.

Maybe I'd add "in the current folder", but I don't run this often enough anyway.

That would be confusing IMHO. The CLI searches all of the benchmark/ subdirectories for benchmarks specified on the command line. It never searches the current working directory.

I've tweaked this a bit after I discovered there is already a benchmark count check both in run.js and _cli.js.

This matches the casing used in run.js.

Marking as dont-land because this depends on #7094, which is semver-major. LMK if I'm wrong.
