Link to full run data from pages page

Currently we show flame graphs and timings: https://bitcoin-dev-tools.github.io/benchcoin/results/pr-41/11797548294/index.html

But it would be nice to link to full data for the run on the `gh-pages` branch, e.g.: https://github.com/bitcoin-dev-tools/benchcoin/tree/gh-pages/results/pr-41/11797548294
