Remove the old v2 benchmarks website (#8805)

## Rationale for this change

The live benchmarks website is now located at
https://github.com/vortex-data/benchmarks-website and it has been going
strong for the past few weeks, so I think it is time to remove this.

## What changes are included in this PR?

Deletes the old website code from here.

## What APIs are changed? Are there any user-facing changes?

N/A
