Add GitHub workflow for benchmarking

Pre review checklist

• Read through the code changes carefully after finishing work
• Make sure tests pass locally (after every commit!)
• Prepare changes in small commits for more convenient review (optional)
• PR title captures the intent of the changes, and is fitting for release notes.
• Updated documentation
• Ensured that unit tests are added for all new behavior (See
  Ground Rules),
  and changes to existing code have good test coverage.

Pre merge checklist

• Added appropriate release note label
• Commit history is consistent and clean, in line with the contribution guidelines.

Really cool! Is this the correct address for the github page with benchmark results https://equinor.github.io/ert/? For some reason the page is blank, maybe I am doing something wrong?🧐

The GitHub action I'm using pushes automatically to the gh-pages branch of ert every time someone commits to main.
It pushes to the file data.js in the folder /dev/bench so the correct url is https://equinor.github.io/ert/dev/bench/

I like it. How could we make sure people know about this? Add a link to github starting page, mention it in the README ...

Perhaps we could show it on the screen in the office?
