Include error stack trace in summary

[dboriichuk]

Currently, when "output-to" input is set to "step-summary", there is no way to see stack traces of detected errors, as such information is contained only in "Annotation Raw output" button.
While this button is available only in "Check" page.

I would like to suggest either have additional input to select if need error message or error details displayed in "Summary" page.

The logic responsible for this is located here
const lines = (tc.error.message ?? getFirstNonEmptyLine(tc.error.details)?.trim())
The goal is to have tc.error.details by default.
