Feature Request: Line break before or after "+"

Describe the Feature
When building a long string in a script for insert or update, I like to break it into logical chunks for readability and easy maintenance. Also, VSCode does not like really long single-line strings. Something like this:

declare @longString nvarchar(max) = '';

set
    @longString = @longString +
	'{"JsonObject": [{' +
	'"JsonField1": {"Name": "JsonValue1"},' +
	'"JsonField2": {"Name": "JsonValue2"},' +
	'"JsonField3": {"Name": "JsonValue3"},' +
	'"JsonField4": {"Name": "JsonValue4"}' + 
	'}]}';


update MyTable set MyColumn = @longString where...

At this time, when formatting with this extension, the formatter joins all these lines onto a single line.

Why do you want this feature?
I'd like to keep my strings readable and not have the issue with VSCode an long strings.

No files or tests are named in the issue. Reproduce the formatter's output with the provided SQL string, then locate the string-concatenation formatting entry point. Done means formatting preserves or supports readable line breaks around "+" without joining the example into one long line, with regression coverage for that case.
