Show suggest widget on trigger characters

[isidorn]

Refs: #131940

Let's change the default of
"editor.inlineSuggest.allowSuggestOnTriggerCharacters": true

Let's keep "editor.inlineSuggest.allowQuickSuggestions": false

After we do that let's double check if Copilot is returning null when we ask them for inline completions after a focused suggest item changes.

After we do that let's double check if Copilot is returning null when we ask them for inline completions after a focused suggest item changes.

I just checked, this seems to be the case.
