Bug: tests fail on Windows because of CRLF line endings

[ahelwer]

Currently on Windows all the "Config On Type Formatting Test Suite" tests and the "TLA On Type Formatting Test Suite" tests all fail with errors of this type:

 1) Config On Type Formatting Test Suite
       Indents constants-block body:

      AssertionError [ERR_ASSERTION]: Expected values to be loosely deep-equal:

[
  'CONSTANTS\r',
  '  '
]

should loosely deep-equal

[
  'CONSTANTS',
  '  '
]
      + expected - actual

       [
      -  "CONSTANTS\r"
      +  "CONSTANTS"
         "  "
       ]

        at Object.<anonymous> (c:\Users\ahelwer\source\vscode-tlaplus\out\tests\suite\formatters\formatting.js:26:16)
        at Generator.next (<anonymous>)

        at processTicksAndRejections (internal/process/task_queues.js:94:5)

This is due to Windows adding the CR (\r) character to line breaks in addition to the LF (\n) character.

Yeah, I've added Windows to the build matrix, and it fails: 1125122153

Windows tests are green again: 1125318149
