Fix delete-artifact in Automatus workflows

[vojtapolasek]

Description:

• add Github token to delete-artifact actions
• specify permissions explicitly so that the delete-artifact can actually delete the artifact

Rationale:

• delete-artifact requires token it since version 4

• I used following linkas as a reference for the fix:

  • https://docs.github.com/en/actions/security-guides/automatic-token-authentication
  • Default token is not read automatically GeekyEggo/delete-artifact#21

Testing hints:

• clone this PR and create a new PR while submitting some change to a rule remediation
• or try to modify already existing PR which exhibits the problem with Automatus workflows and failing delete-artifact action according to this PR
