Slack notification formatting issues - 0.18.14

[data-han]

Is your feature request related to a problem? Please describe. I'm just checking in with regards to the new update 0.18.14 on the new slack design. Awesome to have a new look but i would want to check if we could make it better since this is largely used across by everyone

Describe the solution you'd like https://github.com/great-expectations/great_expectations/pull/9952

I wrote in the feature PR regarding this but not sure if it is 'closed' and won't be looked after. Anyway, my team has been using this slack notification for a long time, it is serving our purpose quite well (except that it had this extra filepath issue, im not sure why is that??) . With the new update, it is not as clear as it was before to show the asset name etc
