Add a refresh button in KV tab in the project page

### What problem are you trying to solve?

https://dash.deno.com/projects/{project-name}/kv has data viewer that helps us browse the data stored in KV.
It would be great if there is a "refresh" button so that we can easily refresh the data without refreshing the whole page.

### Describe the solution you'd like

Place a "Refresh" button somewhere in the data viewer

### Describe alternatives you've considered

Switch between tabs (like "KV" -> "Cron" -> "KV") can refresh the data

Or just use the browser reload
