Multiple instances of AutomaticRetryAttribute are not allowed

[FixRM]

Hello, and thank you for a great tool!

I'm trying to achieve two goals:

1. All failed jobs must be transitioned to deleted state
2. Retries must happen only for specific exception types

I tried the flowing:

GlobalJobFilters.Filters.Remove(typeof(AutomaticRetryAttribute));
GlobalJobFilters.Filters.Add(new AutomaticRetryAttribute()
{
    OnAttemptsExceeded = AttemptsExceededAction.Delete,
    OnlyOn = [ typeof(OperationCanceledException) ]
});
GlobalJobFilters.Filters.Add(new AutomaticRetryAttribute()
{
    Attempts = 0,
    OnAttemptsExceeded = AttemptsExceededAction.Delete
});

Retry works but jobs with other types of errors goes to "Failed" state instead of "Deleted".

Then I tried the following:

GlobalJobFilters.Filters.Remove(typeof(AutomaticRetryAttribute));
GlobalJobFilters.Filters.Add(new AutomaticRetryAttribute()
{
    Attempts = 0,
    OnAttemptsExceeded = AttemptsExceededAction.Delete
});
GlobalJobFilters.Filters.Add(new AutomaticRetryAttribute()
{
    OnAttemptsExceeded = AttemptsExceededAction.Delete,
    OnlyOn = [ typeof(OperationCanceledException) ]
});

In this case all failed jobs goes to deleted without any retry.

I guess the problem is that only one instance of each attribute type is enabled?

@odinserj , if I may ask: Would a PR where one could have different timeouts per exception, would that be accepted, given it's of good quality?
