Update Code Section Format in Readme

[Jordin221]

Describe the bug
Under basic usage, the scorecard argument is copyable along with the output produced when the argument is ran.

Reproduction steps
Steps to reproduce the behavior:

1. visit this link
2. copy the code section
3. paste the code section and observe the results

Expected behavior
We propose separating the command from the output to be copied on its own.

Hi @Jordin221, could you clarify what the desired formatting would be — something like this?

---

Scorecard can run using just one argument, the URL of the target repo:

scorecard --repo=github.com/ossf-tests/scorecard-check-branch-protection-e2e

Sample CLI output:

Starting [CII-Best-Practices]
Starting [Fuzzing]
Starting [Pinned-Dependencies]
[...]
