fix: remove time label from hasura actions prometheus (#395)

## Description

Closes: #XXXX



Due to the time label being different, the monitoring for hasura actions histogram will not accumulate even under the same action name.

Current monitoring: 
```
# TYPE bdjuno_action_response_time histogram
bdjuno_action_response_time_bucket{path="/delegation",time="0.624719333",le="0.5"} 0
bdjuno_action_response_time_bucket{path="/delegation",time="0.624719333",le="1"} 1
bdjuno_action_response_time_bucket{path="/delegation",time="0.624719333",le="2"} 1

```

Updated monitoring:
```
# TYPE bdjuno_action_response_time histogram
bdjuno_action_response_time_bucket{path="/delegation",le="0.5"} 0
bdjuno_action_response_time_bucket{path="/delegation",le="1"} 2

bdjuno_action_response_time_bucket{path="/delegation",le="3"} 2
bdjuno_action_response_time_bucket{path="/delegation",le="4"} 2
bdjuno_action_response_time_bucket{path="/delegation",le="5"} 2
bdjuno_action_response_time_bucket{path="/delegation",le="+Inf"} 2
bdjuno_action_response_time_sum{path="/delegation"} 1.5621203750000001
bdjuno_action_response_time_count{path="/delegation"} 2
```
