Added missing postDownload and deployFirst fields in action editor

[sebjulliand]

Changes

Following up on #3109

This PR adds a Post Execution Downloads and a Deploy before running field to the Action editor for Local Actions only.

Other types of action will not display these fields in the editor.

These fields could only be added and edited manually from the settings/actions.json files.They can now also be changed from the editor.

The postDownload field also now supports variables replacement when the action is executed.

The PR also makes sure that some optional action fields are cleaned up before being saved to avoid writing blank strings/empty array in the settings.

How to test this PR

1. Edit an action
2. Set one or more post execution download paths
3. Save
4. The paths must be saved as an array in the settings
5. Remove the paths
6. Save
7. The postDownload array must be removed from the settings

@sebjulliand The actual change in the PR is working as expected. But noticed some odd behavior when testing.

When editing local actions, for some reason the edits to the following are not being saved to the actions.json file:

• Command(s) to run
• Environment
• Refresh
• Run on protected/read only

Some of these don't seem to be editable on main either actually so likely unrelated to this PR. But Command(s) to run for example does work on main but not on this branch so semi-related 🤔

@SanjulaGanepola I fixed the command not being updated; that was a bug from this PR. Well spotted!
But I couldn't get the other fields to fail to be updated.

By any chance, do you have actions with duplicated names in you local actions? That could explain the issue.

Added a checkbox in the editor for the deployFirst local actions field.
