Source risk assessment table content is mixed up

[pohlarized]

On the scorecards home page, the table labeled "Source risk assessment" contains the following two rows:

| [Branch Protection](https://github.com/ossf/scorecard/blob/main/docs/checks.md#branch-protection)  | Does the project avoid dangerous coding patterns in GitHub Actions?                                                                                   | High     |
| [Dangerous Workflow](https://github.com/ossf/scorecard/blob/main/docs/checks.md#branch-protection) | Does the project use [Branch Protection](https://docs.github.com/en/free-pro-team@latest/github/administering-a-repository/about-protected-branches)? | Critical |

These have two issues.

1. The link for "Dangerous Workflow" actually links to the "Branch Protection" docs
2. The descriptions of "Dangerous Workflow" and "Branch Protection" are switched up
