fix(amazonq): Use document change event for auto trigger classifier input

[leigaol]

Problem

The auto trigger classifier needs the entire document change event as input to correctly predict whether to make auto trigger or not. This code path was lost when we migrate inline completion to Flare (language server).

Solution

Implement the IDE side changes for below PRs:

aws/language-server-runtimes#618

aws/language-servers#1912
