Whitespace removed when "Code Formatting: Whitespace Around Operator" Enabled

Prerequisites

• I have written a descriptive issue title.
• I have searched all issues to ensure it has not already been reported.
• I have read the troubleshooting guide.
• I am sure this issue is with the extension itself and does not reproduce in a standalone PowerShell instance.
• I have verified that I am using the latest version of Visual Studio Code and the PowerShell extension.

Summary

When enabling the "Whitespace Around Operator" formatting option, which description reads "Adds spaces before and after an operator...", the setting will also remove redundant whitespace around operators, despite the description not detailing that.

This means that if a user deliberately adds additional whitespace in order to line up declarations, that deliberate extra whitespace is removed and their declarations no longer cleanly line up.

From my perspective, the removal of the additional whitespace should be moved to it's own separate preference, which is how it already operates for "Add Whitespace Around Pipe" and "Trim Whitespace Around Pipe". For these settings related to pipes, the Add setting only adds, and the Trim setting only removes. Or at the very least, the dual nature of "Whitespace Around Operator" should be detailed in it's description.

---

While not directly related to the bug itself, I could also very easily see an argument being made to have an option similar to "Align Property Value Pairs" when multiple variable declarations are made on consecutive lines, like in the instance of my example below. At least for my personal preference a setting like that could also be an reasonable solution to this problem.

Steps to Reproduce

1. Enable the "Code Formatting: Whitespace Around Operator" preference
2. Write code with multiple spaces between variable name and operator
3. Apply formatting

Visuals

Input

$foo 	 = 'bar'
$testing = 'stuff'
$month='March'

Expected behavior (based on description text that only mentions adding whitespace)

$foo 	 = 'bar'
$testing = 'stuff'
$month = 'March'

Actual behavior

$foo = 'bar'
$testing = 'stuff'
$month = 'March'

Logs

No response

Start by reproducing the formatting behavior with the "Whitespace Around Operator" preference and the variable declarations shown in the issue. Inspect the formatter implementation and its related tests; no file or test paths are named in the report. Done means the documented add-whitespace behavior is consistent with the handling of existing extra whitespace, with coverage for the reported input.
