Update GitHub Actions code example "with" syntax to map instead of array

[Shegox]

Why:

The GitHub Action examples on the codeql page (https://docs.github.com/en/free-pro-team@latest/github/finding-security-vulnerabilities-and-errors-in-your-code/configuring-code-scanning) use the "with" as an array, but this needs to be a map (see the actions docs here).

What's being changed:

Update GitHub Action code snippet on the "configuring code scanning" page to use correct map syntax for the variables in the "with" attribute instead of the array syntax.

Check off the following:

• All of the tests are passing.
• I have reviewed my changes in staging.
• For content changes, I have reviewed the localization checklist
• For content changes, I have reviewed the Content style guide for GitHub Docs.
