Updating the script via API does not show update in the Kestra UI

[aucubin]

Describe the issue

Repro:

• Change something on a namespace file in the Kestra UI and save it. After refreshing the page the change should still be there.
• Upload an older version of the namespace file via the api/v1/namespaces/$namespace/files route using curl or some other tool.
• Refresh the UI tab from before and you will see that the change from the API request is not there.
• The only way to see that the API change was applied is by exporting the namespace files via the API or by disabling the cache in the network tools and then refreshing the tab.

Environment

• Kestra Version: 0.21.3
