Autocompletion for the "error" property is aware of taskId but not aware of message and stackTrace properties

[anna-geller]

Describe the issue

We should extend the autocompletion if possible so that users don't have to look up those error properties

To reproduce:

id: errors
namespace: company.team

tasks:
  - id: hello
    type: io.kestra.plugin.core.log.Log
    message: Starting the workflow
  - id: fail
    type: io.kestra.plugin.core.execution.Fail

errors:
  - id: error-log
    type: io.kestra.plugin.core.log.Log
    message:
      - "It's the fault of '{{ error.taskId }}'"
      - "See the message: {{ error.message }}"
      - "{{ error.stackTrace }}"

Environment

• Kestra Version: develop
