Do not force snippet suggestions to the bottom of completions

[juliasilge]

Currently, we force snippet suggestions to the bottom of the completions list:

quarto/apps/vscode/package.json

Line 899 in d818dd0

"editor.snippetSuggestions": "bottom",

If we don't force this, then they will go wherever the underlying embeddedCodeCompletionProvider wants them to go. I'll install the new .vsix in VS Code and Positron to show where snippets show up with this proposed change.

Before this PR, snippets were always pushed down to the bottom of the completions list. With this new change, the snippets go wherever the underlying completion provider puts them.

For example, in VS Code with vscode-R extension, the snippet for lib is set with the snippetSortOrder of "inline", which means alphabetically with everything else:

In Positron, the R snippets are set to show up with snippetSortOrder of "top":

Quarto probably shouldn't interfere with this ordering.

I'm a little weirded out by the sheer volume of configuration options that quarto tweaks on its own. Maybe we should consider trimming this down in the future.

I find it quite hard to figure out "who" modified settings like these in the UI. The Settings UI reports "modified elsewhere" but you look in your user / project settings and can't see it being modified so you're left scratching your head about them.

I agree with the sentiment, but I sort of trust that they were put there for a reason, and am left agreeing with the goal, but unable to come up with a plan to do it that I like.
