fix: slack notification url

[cre8ivejp]

Fixes #821

After the Organization implementation, we must use the url_code instead of environment_id for all URLs.
I fixed it to use the urlCode and added environmentName to the notification, too.

This pull request mainly involves changes in the pkg/batch/jobs/notification/domain_event_informer.go and pkg/notification/sender/notifier/slack.go files, with changes focusing on the replacement of environmentID with environmentName and environmentURLCode. This is reflected in the creation of notification events, handling of messages, and logging. Test files have been updated to reflect these changes. Additional logging has also been added in pkg/eventpersister/persister/persister.go.

Changes to domain_event_informer.go:

• Added logging for when the DomainEventInformer fails to pull a message from the message channel.
• Replaced environmentID with environmentName and environmentURLCode in handleMessage and createNotificationEvent methods. [1] [2] [3] [4]

Changes to domain_event_test.go:

• Updated test cases to use environmentName and environmentURLCode instead of environmentID. [1] [2] [3] [4]

Changes to other files:

• Replaced environmentID with environmentName and environmentURLCode in various files and methods. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16]
• Added debug logging in pkg/eventpersister/persister/persister.go when the update evaluation count timer is triggered.

I have commented on some points of interest.

And one more thing,
Isn't it necessary to take measures such as returning an error if environmentURLCode is empty in createNotificationEvent() etc.?

As default, the url_code is a required field. So there is no need.
