Fix misleading error message for out-of-range --retry-failed-tests-delay values

[Copilot]

Bug Fix

What was the bug?

RetryFailedTestsDelayOptionInvalidArgument was the single error message for both parse failures and range violations. For syntactically valid but out-of-range inputs (e.g. 25d), the message "requires a valid time span value" was misleading — the value is valid, just too large for Task.Delay (capped at int.MaxValue ms).

How did you fix it?

Updated the error message to explicitly state the allowed range:

Option '--retry-failed-tests-delay' requires a valid time span value that is non-negative and no greater than 2147483647ms (~24.20:31:23.647) (e.g. 200, 1s, 2.5m, 1h)

Updated ExtensionResources.resx and all 13 .xlf locale translation files accordingly.
