Completing NBT values inserts a duplicate end quote

[misode]

Example:

execute if predicate {condition:""}

When autocompleting inside the quotes, it results in this:

execute if predicate {condition:"all_of""}

[misode]

Disabling the insertReplaceSupport capability fixes this (but at what cost?)

Also strange that this works fine in JSON files, which leads me to believe that vscode decides to not use insert mode for JSON strings.

vscode decides to not use insert mode for JSON strings

This is indeed the case, as the built-in JSON extension contributes a default configuration to use replace mode instead of insert mode

https://github.com/microsoft/vscode/blob/35ac2d01a6b7ae2e0141377a6a924f050aa65237/extensions/json-language-features/package.json#L135

I think we can similarly add a default configuration in packages/vscode-extension/package.json to use replace mode for mcfunction as well? I can't tell why anyone would prefer the insert mode tbh.
