20655	"Command line option ""update plugins"""	skyper	team	"==== What steps will reproduce the problem?
1. Start JOSM
1. Open plugin preferences
1. Update plugin list
1. Get warning about updates for plugins
1. Update plugins
1. Warning about required restart

==== What is the expected result?
An option to manually trigger a plugin update on start-up.

==== What happens instead?
No option available.

==== Please provide any additional information below. Attach a screenshot if possible.
This request somehow overlaps with #19211. 
I do not care if the command line option only updates the plugins and exits or if JOSM starts with an automatic plugin update on start-up.
