Indent and dedent shortcuts unavailable on some keyboards

[zeniko]

The #IndentSnippet and #UnindentSnippet shortcuts defined in LeSnippetElement class >> #initializeKeyboardShorcuts are currently primary + bracket.

On some keyboards such as my de-CH one, brackets however have to be entered by [AltGr]+key or [primary]+[secondary]+key, so that (un)indenting by keyboard doesn't work at all.

For me, I've redefined the shortcuts to

LeSnippetElement keyboardShortcuts
	at: #IndentSnippet
		put: BlKeyCombinationBuilder new alt shift arrowRight build;
	at: #UnindentSnippet
		put: BlKeyCombinationBuilder new alt shift arrowLeft build.

which is also consistent with moving snippets up and down (which are [secondary]+[shift]+[arrow]).

Please consider at least adding these shortcuts (if not replacing the bracket-based ones) for international keyboards. Thanks.
