Update taskTemplates.ts

[html] auto indentation is different if the closing tag is followed by any character or whitespace. Fixes Microsoft/vscode#37869

Very tiny fix, the template for maven kept a taskName (old style) element.

Experiment with two compilation units

Start moving html ext to strict mode compile

Move css extension to strict

* Marked output code-line

* First Idea on where to get the platform

* Add platform info in code --version #37793 Done

* Add CodeAction Type

Adds skeleton on a new CodeActionType and allows codeActionProvider to return either `Command`s or `CodeAction`s

Move proposed CodeAction API to proposed and try using it in TS

Split CodeAction into quickfix and refactoring classes

Update proposed interface

Update for new API

Adding basic docs

* Support workspace edits and text edits in codeactions

* Remove placeholders

* Resolving conflicts and making PR suggested changes

* Fix quick fix test

* Revert change to only use `CodeAction` instead of `CodeAction | Command` in modes since this will break `vscode.executeCodeActionProvider`
