parse job events to extract failure messages

[d-honeybadger]

Description of your changes

Follow-up for #228
In #294, we set the Ready condition, but the message on the condition was just the ansible-runner's exit code.
In this PR, the message is enhanced with the failure reason(s) from ansible logs.

Btw, parsing these job events can also help with #290 - there's a "summary" event at the end of playbook execution wich has the same info as ansible summary in the logs

I have:

• Read and followed Crossplane's contribution process.
• Run make reviewable to ensure this PR is ready for review.
• Added backport release-x.y labels to auto-backport this PR if necessary.

How has this code been tested

Created an ansiblerun with a failure, an unreachable host, and successful execution.
Here are examples of the conditions of the failed ones:

  - lastTransitionTime: "2024-02-15T22:29:06Z"
    message: 'observe failed: running ansible: exit status 2: Failed on play "test",
      task "file", host "test": file (/test4) is absent, cannot continue'
    reason: ReconcileError
    status: "False"
    type: Synced

  - lastTransitionTime: "2024-02-15T19:55:58Z"
    message: 'observe failed: running ansible: exit status 4: Unreachable on play
      "test", task "Gathering Facts", host "test": Failed to connect to the host via
      ssh: [email protected]: Permission denied (publickey,password).'
    reason: ReconcileError
    status: "False"
    type: Synced
