Add next steps to the query library

[elad-pticha]

After finding a vulnerable workflow, each query should have a follow-up action to mitigate the risk.

For example,
After finding a workflow that is vulnerable to issue title injection, we would like to give next steps for users of how they can mitigate the risk.

This can be done by adding another property to each query called: fix (could be something else) that will contain a short explanation about the mitigation process.
