`AuditEntry` missing relevant fields

[patriknordlen]

Similar to #2534 and #2669.

There are many event type specific fields included in audit log events returned by the API that are not included in AuditEntry.

These are the ones that I've noticed are missing, though there might be more than these as well.

• actor_ip - IP of actor (if enabled in GitHub audit logs)
• actor_location - location of actor (country code etc)
• hashed_token - hashed token identifier when an action is performed using an access token
• job_workflow_ref - reference to workflow job when a workflow runs
• oauth_application_id - OAuth application identifier when an OAuth application performs an action
• org_id - organization numeric ID
• programmatic_access_type - type of programmatic access (i.e. via token, cli, oauth app...)
• pull_request_id - self-explanatory
• pull_request_title - self-explanatory
• pull_request_url - self-explanatory
• reasons - Used when a user overrides branch protection, includes info on user's stated reason why
• run_number - the numerical ID of the workflow run
• token_id - token ID when an action is performed using an access token
• token_scopes - string containing scopes assigned to a token
• topic - topic used in workflow runs
• user_agent - user-agent used in performing an action
