[FR] Unify some of the preferences

[marcjulianschwarz]

Proposed Changes

• unify "Excluded Folders"
• unify "Search Content"
• unify "Template for Append Action" and "Template for Append Selected Text Action"
• unify "Remove Content" options

These preferences should be left independent:

• show detail
• show metadata
• primary action

Use Case

• Users won't have to fill in the preferences for each command (gets worse when more commands will be added).
• Makes preferences more "visible"

In the same vein, use new file picker input for vault path.
