Merge #12187: [Docs] Updating benchmarkmarking.md with an updated sample output

b21244e Updating benchmarkmarking.md with an updated sample output and help options (Jeff Rade)

Pull request description:

  This PR is just a documentation update for someone (or myself) that looks into finishing up #7883 in the future.

  Looked through #7883 and appears [ryanofsky's PR](bitcoin/bitcoin#8873) setup the benchmarks, but there are `FIXME` comments to pull in data from `test/` to get a larger data set (assuming reason why 7883 is still open).

 Bitcoin Core has an internal benchmarking framework, with benchmarks
 for cryptographic algorithms such as SHA1, SHA256, SHA512 and RIPEMD160. As well as the rolling bloom filter.
 
+Running
+---------------------
 After compiling bitcoin-core, the benchmarks can be run with:
-`src/bench/bench_bitcoin`
+
+    src/bench/bench_bitcoin
 
 The output will look similar to:
 ```
